The Family of Amos Plimpton & Mary Guild
of Medfield, Massachusetts, 1735 – 1808
This family biography traces the lives of Amos Plimpton (1735–1808) and his first wife, Mary Guild (1735–1800), colonial New Englanders whose lives unfolded against the dramatic backdrop of the American Revolution and the founding of a new nation. Rooted in the small town of Medfield, Massachusetts for generations, the Plimpton family story is one of land, loyalty, and legacy — a family that literally lived on the same ground their ancestors had cleared more than a century before.
Amos Plimpton: Early Life and Family Origins
Amos Plimpton was born on 16 June 1735 in Medfield, Suffolk County, Massachusetts Bay Colony — a prosperous farming community about twenty miles southwest of Boston. He was the second child and second son of John Plimpton (1708–1756) and Abigail Fisher (1711–1785), who had married in Medfield in 1731. The Plimpton family were well-established residents of Medfield, having held land there for multiple generations, and their homestead would remain a central feature of Amos's entire life.
The town of Medfield in the 1730s was a close-knit Puritan community, largely agricultural, where families like the Plimptons were known as yeomen — independent landowners who farmed their own land. Colonial New England life revolved around the rhythms of the seasons, the church, and the community, and a second son like Amos would have grown up working the family farm, learning the skills of husbandry that would serve him throughout his long life.
Parents
John Plimpton (1708–1756) and Abigail Fisher (1711–1785) raised their family on the ancestral Plimpton homestead in Medfield. John died in 1756, the same year Amos married, leaving Abigail a widow. She lived until 1785, and upon her death, Amos — as the surviving son on the property — took possession of the family estate, settling the inheritance by paying out shares to his siblings.
Siblings
Amos grew up alongside four brothers and sisters, a typical colonial New England family:
- John Plimpton — Born before 27 January 1731/32 in Medfield. The eldest child, John predeceased his father, dying on 22 April 1754 at just twenty-two years of age, leaving Amos as the eldest surviving son.
- Olive Plimpton — Born before 8 February 1737 in Medfield. She married Adam Peters on 5 May 1758 in Medfield and died young, on 12 September 1768, still in Medfield, at around thirty-one years of age.
- Abner Plimpton — Born before 6 May 1742 in Medfield. Abner eventually moved north, dying in Vermont in 1814. He and his wife Esther appear in a land transaction with Amos in 1765, suggesting the siblings maintained close ties even after Abner relocated.
- Unity Plimpton — Born before 6 January 1746 in Medfield. She married Benjamin Boyden on 22 December 1758 in Medfield and lived a long life, dying in 1828 in Medfield at approximately eighty-two years of age.
Mary Guild was born in 1735 in Walpole, Suffolk County, Massachusetts Bay Colony — the same year as her future husband Amos, though in a neighboring town about ten miles to the south of Medfield. She was the eldest daughter of Nathaniel Guild (1712–1796) and Mary Boyden (1708–1776), who had married in Dedham in 1733. The Guild family were also established New England colonists with deep roots in the region.
Walpole in the 1730s was a young town, having been set off from Dedham only in 1724, and the Guild family were among its early settlers. Mary would have grown up in this formative community, surrounded by the rhythms of colonial farm life much like Amos in Medfield. How and when she and Amos met is not recorded, but Walpole and Medfield shared social and religious connections — marriage across neighboring towns was common — and the two likely met through church or community gatherings.
Parents
Nathaniel Guild (1712–1796) lived to the remarkable age of about eighty-four, outliving his wife Mary Boyden (1708–1776) by twenty years. In his 1795 will, Nathaniel divided his estate equally among his surviving children, with Mary Plimpton (née Guild) receiving a one-seventh share of both his real and personal estate. After Nathaniel's death in 1796, the heirs came together in 1798 to sell the family lands in Walpole to Harman Guild, with both Amos and Mary signing the deed alongside Mary's siblings.
Siblings
Mary was the oldest of six children in the Guild family, and the records show that most of her siblings settled in communities across Norfolk and Bristol counties:
- Nathaniel Guild (born 29 May 1739, Walpole) — Married Rebecca Hart on 21 September 1767 in Walpole. He died on 4 April 1793 in Stoughton, Norfolk, Massachusetts, predeceasing his father.
- Mercy Guild (born about 1742, Walpole) — Married Ebenezer Hewins on 2 May 1761 in Walpole. She lived a long life, dying about 1820 in Walpole at approximately seventy-eight years of age.
- Susanna Guild (born 3 August 1744, Walpole) — Married Ezra Morse on 13 April 1765 in Walpole. She died on 11 January 1822 in Roxbury, Massachusetts.
- Samuel Guild (born 13 October 1746, Walpole) — Married twice: first to Elizabeth Ferguson in 1770, and after her death, to Katherine Leonard in 1786. He died on 11 May 1816 in Easton, Bristol County.
- Mehitable Guild (born about 1752, Walpole) — Died on 12 February 1816 in Massachusetts. She appears to have remained unmarried, as she is listed as a 'spinster' in the 1798 deed settling her father's estate.
Amos Plimpton and Mary Guild were married on 9 December 1756, in Medfield, Massachusetts. The Medfield Vital Records book records the union simply as 'Amos Plimpton and Mary Guild, Dec. 9, 1756.' Amos was twenty-one and Mary twenty-one, both marrying at a typical age for colonial New England. The year of their marriage was also the year Amos's father John Plimpton died, suggesting Amos was stepping into adulthood and the responsibilities of head of household in rapid succession.
The couple made their home on the original Plimpton homestead in Medfield. This was no ordinary house — it was a place layered with family history. According to the town historian Mr. Tilden, the original Plimpton house had long since decayed and been replaced by a second structure, a two-story house with a single large room below and a front door at the westerly end, to which a lean-to had been added in the rear. This was the house into which Amos and Mary moved as newlyweds, and where they would raise their children and live out most of their lives.
Together, Amos and Mary would share forty-four years of marriage until Mary's death in 1800. Their partnership weathered the deaths of three young children, the upheaval of revolution, and the gradual passing of their parents' generation, as Amos and Mary grew into the matriarchs and patriarchs of the Medfield community they had always called home.
Children of Amos Plimpton and Mary Guild
Amos and Mary had five children, though sadly three died in infancy or early childhood — a common and heartbreaking reality of colonial life:
- Molly Plimpton (born 8 May 1758, Medfield) — The eldest child and only daughter to live to adulthood. Molly married twice: first to Joseph Cole on 29 June 1780 in Medfield, and after his death, to Amos Kingsbury on 14 April 1785. The Kingsburys settled on the original Plimpton homestead alongside her father, a fact that would shape the later chapters of the family story. Molly died on 27 January 1813 in Medfield, Norfolk County, Massachusetts.
- Elizabeth Plimpton (born 14 June 1761, Medfield) — Died on 2 May 1766, just a few weeks short of her fifth birthday.
- John Plimpton (born 22 September 1763, Medfield) — Named for his grandfather, young John lived only two years, dying on 9 October 1765.
- Amos Plimpton (born 25 March 1770, Medfield) — Named for his father, this child lived only two months, dying on 26 May 1770. The loss of three children within a few years must have been an especially sorrowful season for the family.
- Mercy Plimpton (born 9 September 1772, Medfield) — The youngest child. Mercy married Aaron Smith on 6 October 1795 in Medfield and lived a long life, dying on 13 April 1850 in Medfield, Norfolk County, Massachusetts, at the age of seventy-seven.
Like most New England yeomen of his era, Amos Plimpton's wealth and status were tied closely to land. The historical record preserves several significant property transactions that illuminate his economic life and place in the community.
In March 1765, Amos purchased a one-fifth share of a 45-acre tract of woodland lying in the northern part of Wrentham from his brother Abner and Abner's wife Esther, paying twelve pounds. The woodland was bounded on the north by the Charles River — valuable timberland in colonial New England. Just months later, in September 1765, Amos sold the same parcel to David Wight, a yeoman of Medway, for twelve pounds and six shillings, netting a small profit. This kind of property trading was a common way for colonial farmers to manage assets and generate income.
The most significant property event of Amos's life came in 1785, when his mother Abigail Fisher Plimpton died. As the surviving son on the homestead, Amos inherited the ancestral estate, paying out shares to his siblings Abner Plimpton, Unity Boyden, and the heirs of Olive Peters. The old Plimpton homestead — with its layered history of original structures, rebuildings, and additions — was now entirely his. The genealogist Levi B. Chase noted that Amos 'was the last of the name residing on the original homestead,' a distinction that speaks to both his attachment to the land and his family pride.
In 1798, Amos and Mary joined her siblings in selling the Guild family lands in Walpole, following the death of her father Nathaniel Guild in 1796. The deed, a remarkable document listing all the Guild heirs, records Amos as 'Yeoman' and Mary as his wife, and together they received their portion of the $1,671.43 paid by Harman Guild for the family property.
Amos Plimpton and the American Revolution
Among the most remarkable chapters of Amos Plimpton's life is his service in the American Revolution. He was thirty-nine years old when the war began, hardly a young man, yet he answered the call to arms with unmistakable commitment.
His military career began on 19 April 1775 — the very day of the Battles of Lexington and Concord, the opening shots of the Revolutionary War. Amos marched out with Captain Ephraim Chenery's Medfield company, part of Colonel John Smith's regiment, responding to the alarm that the British Regulars were on the move. He served eleven days in this initial mobilization. It is a striking thought: on the day that 'the shot heard round the world' was fired at Concord, Amos Plimpton was among the Massachusetts militiamen who dropped their tools and marched toward the sound of the guns.
His service continued into 1776. He was commissioned as Second Lieutenant in Captain Aaron Guild's company — notably, a Guild, perhaps a relative of his wife Mary — under Colonel Lemuel Robinson's regiment. He enlisted on 29 January 1776, and the regiment served at Dorchester Heights in late March 1776. The fortification of Dorchester Heights was a pivotal moment in the war: General George Washington directed the placement of cannons captured at Fort Ticonderoga, overlooking Boston Harbor, which compelled the British to evacuate Boston on 17 March 1776 without a battle. Amos was present for this decisive strategic victory.
He also served as a Lieutenant in Captain Sabin Mann's Medfield militia company, and by September 1777, his name appears on a list of men who paid money in lieu of service for the Continental Army quota — Amos paid £15. By this point he was forty-two years old, a property-owning farmer with family responsibilities, and the payment reflects a common and accepted practice for established householders who could not leave their farms for extended service.
Amos's gravestone at Vine Lake Cemetery in Medfield identifies him as 'Lieut. Amos Plimpton,' a permanent acknowledgment of his military rank and service. His record in Massachusetts Soldiers and Sailors of the Revolutionary War stands as testimony to a man who served his town, his colony, and his new nation across multiple campaigns and years.
Later Years
The 1790 and 1800 Censuses
The federal censuses of 1790 and 1800 offer brief but vivid snapshots of the Plimpton household. In 1790, Amos appears in Medfield with one male over sixteen (himself) and one female (Mary), suggesting their daughters had left home or the household was otherwise small at that time. By 1800, the census records one male over forty-five (Amos, now sixty-five) and one female aged twenty-six to forty-five (perhaps his daughter Molly). It is a quiet portrait of a couple growing old together.
Mary (Guild) Plimpton's Death
Mary (Guild) Plimpton, Amos's wife of forty-four years, died on 20 March 1800 in Medfield. She was sixty-four years old. The loss of a life partner of such long standing must have been profound for Amos, then sixty-four himself. The household they had built together — the farm, the children, the community ties — now continued without her.
Second Marriage
Later in 1800, Amos married for a second time. His new wife was Mary (Pratt) Breck (1750–1843), widow of Elijah Breck of Sherborn. The Medfield Vital Records note the intention of marriage on 6 November 1800, just seven months after Mary Guild's death. Mary (Pratt) Breck was fifty years old at the time of the marriage, fifteen years younger than Amos. She would outlive him by thirty-five years, dying on 11 December 1843 at the extraordinary age of ninety-three in Medway, Massachusetts, and was buried at Prospect Hill Cemetery in Millis.
The town historian Mr. Tilden records a charming domestic detail about this second marriage: when Amos remarried in 1800, his son-in-law Amos Kingsbury was still living in the house, and 'the house being found too small, a new part was added to the west end, of about the same shape and size as the old part.' Even in his mid-sixties, Amos was expanding and improving the ancient family home.
Amos Plimpton's Will and Final Years
On 13 January 1807, Amos Plimpton wrote his last will and testament — a careful, detailed document that reveals the shape of his world in his final years. He was seventy-one years old, described as 'Gentleman' in the probate records, a step up in social designation from the 'Yeoman' of his earlier years.
The will opens with careful provision for his widow, Mary (Pratt) Plimpton: she was to have use of the front room, bedroom, back room, and back chamber of the dwelling house, together with half the cellar, the well, yard room, and half the wood house. Beyond shelter, Amos specified an annual allotment for her support in rich and specific detail: eight cords of firewood, five bushels of Indian corn, five bushels of rye, one bushel of malt, one barrel of cider, sixty pounds of pork, fifty pounds of beef, sixty pounds of cheese, thirty pounds of butter, ten pounds of flax, and five pounds of sheep's wool. This extraordinary list paints a vivid picture of colonial New England farm life — a largely self-sufficient household economy where everything from food to fiber was produced at home.
The bulk of the estate — all real property including buildings and lands — went to his grandson John Kingsbury, son of his daughter Molly and her husband Amos Kingsbury. The exception was a woodlot at 'Smith's Plane,' which Amos gave to his younger daughter Mercy Smith (wife of Aaron Smith), along with six hundred dollars to be paid in annual installments of one hundred dollars over six years. Amos's wearing apparel went to his son-in-law Aaron Smith; his farming tools to grandson John Kingsbury. The remaining personal estate was divided equally among his two sons-in-law (Amos Kingsbury and Aaron Smith) and grandson John Kingsbury.
The will was witnessed by John Baxter, Thaddeus Moore, and Alpheus Fisher. It was proved in the Norfolk County Probate Court on 6 September 1808, with John Kingsbury named as executor.
Death and Burial
Amos Plimpton died on 20 August 1808 in Medfield, Massachusetts, at the age of seventy-three. He was buried at Vine Lake Cemetery in Medfield, where his gravestone still stands. The inscription carved there reads:
In Memory of
Mr. Amos Plimpton.
Died August 20th 1808
Aged 73
How peaceful are our slumbers here,
No cares disturb our rest,
In vain shall death alarm our fear,
Since Christ the grave hath blest.
These epitaph verses, common in New England Congregationalist tradition, speak to a faith that was a bedrock of Amos's community throughout his life. He was a man who had seen war, buried three children, outlived his first wife of four decades, and carried the family homestead through seventy-three years of colonial and early American history.
The Plimpton Homestead: A Living Legacy
Perhaps no detail in Amos Plimpton's story is more evocative than the fate of the old family homestead. The Plimpton house in Medfield was, by the time historian William Tilden wrote about it in 1887, already a memory. The second house — the two-story structure that Amos and Mary had called home — stood until about 1875, when it was torn down and a new house built by William Kingsbury (grandson John's son) on the same cellar. In Tilden's words, Amos had been 'the last of the name residing on the original homestead.'
Through his daughter Molly and her son John Kingsbury, the land passed out of the Plimpton name but remained in the family bloodline. The brook, the field, the street lot — all the pieces of the estate Amos had tended — were gradually sold for house-lots as Medfield grew into the nineteenth century. The homestead that John Plimpton had established generations before, that Amos had inherited and improved and loved, was absorbed at last into the expanding town around it.
But the story did not end there. Amos's daughter Mercy and her husband Aaron Smith carried the family forward into the 1850s. His grandson John Kingsbury, named in the will as executor and heir, was the keeper of the flame for the next generation. And the name Plimpton, though no longer attached to that Medfield address, lived on in the records of a town shaped by the quiet, enduring work of families like Amos and Mary's.
