2) For the Claude AI biography, I attached a PDF of the genealogical sketch for the specific ancestors using the plus (+) icon, and then prompted the AI tool with: "You are an expert genealogist and family historian. Please create a biography based on information in the attached file for the Jeremiah and Abigail (Peirce) Knowlton family. Include parents, siblings, spouses and children (with birth and death dates and places). Summarize life events, add historical events as appropriate, but do not add or embellish any extra genealogical details. Use section headings. Expand the information in each section to add more details. The tone should be engaging and suitable for family members."

The Jeremiah and Abigail (Peirce) Knowlton Family of Massachusetts (1745–1797)
Jeremiah Knowlton — Early Life
On 3 March 1745, in the township of Concord, Middlesex County, Massachusetts Bay Colony, a boy named Jeremiah Knowlton came into the world. He was the fourth son and fifth child of Jeremiah Knowlton Sr. (1713–1752) and his wife Sarah Allen (1717–1796), who had wed in Sudbury, Middlesex, in 1735. Young Jeremiah grew up in Concord — a town that would, just three decades later, become forever famous as the site of the first shots of the American Revolution. Jeremiah's official birth record, preserved in Concord's town vital records, reads simply:
"Jeremiah Knowlton, the son of Jeremiah Knowlton and Sarah his wife was born March 3: 1745."
Sadly, Jeremiah's father died in 1752 when little Jeremiah was only seven years old, leaving his mother Sarah to raise the surviving children on her own in Concord. It's a testament to Sarah's resilience that she lived to the impressive age of 79, seeing out the Revolution entirely.
The children in the family included:
The woman who would become Jeremiah's wife, Abigail Peirce, was born on 12 April 1750 in Waltham, Middlesex County, Massachusetts Bay Colony. She was the sixth of nine children born to Samuel Pierce (1712–1772) and his wife Abigail Stearns (1715–1796), who had married in Waltham in 1739. The family straddled the border between Watertown and Waltham, with children being born in both towns across the years.
Life in the Peirce household was touched by real tragedy. Of the nine children Samuel and Abigail raised, three died in childhood. These losses were heartbreakingly common in colonial New England, where childhood illness claimed lives with devastating regularity.
The family included these children:
On 4 April 1771, twenty-six-year-old Jeremiah Knowlton and twenty-year-old Abigail Peirce were married in Waltham, Middlesex County. It's worth noting that Jeremiah's own sister Abigail had already married into the Peirce family back in 1759 — so in a lovely twist, Jeremiah was marrying into a family already connected to his own. The marriage was recorded in both the Waltham and Lexington vital records, which tells us that Jeremiah was living in Lexington at the time of the wedding while Abigail was from Waltham.
In March 1773, just two years into their marriage, Jeremiah made a significant investment in the family's future by purchasing three tracts of land from a John White of Charlestown for 77 pounds lawful money. The purchase included a one-acre parcel in Lincoln with a dwelling house and barn, a substantial 40-acre tract of upland and meadow partly in Lincoln and partly in Sudbury, and a 4-acre woodlot in Sudbury. For a young cordwainer (shoemaker) establishing himself in the colony, this was a meaningful commitment to putting down roots.
Together, Jeremiah and Abigail had two daughters in Lincoln:
A Family Torn Apart: Abigail's death
Tragedy struck the young Knowlton family in the dead of winter. On 2 February 1776, Abigail (Peirce) Knowlton died in Lincoln at just 25 years of age. The cause is not recorded, but early death in childbirth or from illness was all too common for young colonial women, and she had given birth to little Abigail just two years earlier. The Lincoln town records mark her passing with quiet simplicity:
The children in the family included:
- John Knowlton, born 4 April 1736, Concord; died 10 May 1737, age 1
- Abigail Knowlton, born 19 January 1739, Concord; married John Pierce, 1759; died 19 January 1813, Westminster
- Nathaniel Knowlton, born 13 June 1741, Concord; married Elizabeth Parks, 1761; died 16 September 1798, Wayland
- Benjamin Knowlton, born 6 November 1743, Concord; no further record
- Jeremiah Knowlton, born 3 March 1745, Concord; subject of this sketch
The woman who would become Jeremiah's wife, Abigail Peirce, was born on 12 April 1750 in Waltham, Middlesex County, Massachusetts Bay Colony. She was the sixth of nine children born to Samuel Pierce (1712–1772) and his wife Abigail Stearns (1715–1796), who had married in Waltham in 1739.

Life in the Peirce household was touched by real tragedy. Of the nine children Samuel and Abigail raised, three died in childhood. These losses were heartbreakingly common in colonial New England, where childhood illness claimed lives with devastating regularity.
The family included these children:
- Abigail Peirce (1st), born 25 May 1740, Watertown; died Sep 1747, age 7
- Samuel Peirce, born 1 November 1741, Watertown; married Ruth Lee, 1768; died 30 March 1806, Watertown
- Elizabeth Peirce, born 30 September 1743, Watertown; married Timothy Flagg, 1761; died 18 March 1808
- Daniel Peirce, born 1 October 1746, Waltham; died 12 September 1747
- Nathaniel Peirce, born 22 November 1748, Waltham; died 24 December 1749

- Judith Peirce, born 8 March 1753, Watertown; married Elisha Stearns, 1778; died 30 August 1805, Watertown
- Ezra Peirce, born 24 December 1755, Watertown; died 6 August 1795, Watertown
- Beulah Peirce, born 8 July 1764, Watertown ; married John Colburn, 1784; died 7 September 1816, Lincoln
On 4 April 1771, twenty-six-year-old Jeremiah Knowlton and twenty-year-old Abigail Peirce were married in Waltham, Middlesex County. It's worth noting that Jeremiah's own sister Abigail had already married into the Peirce family back in 1759 — so in a lovely twist, Jeremiah was marrying into a family already connected to his own. The marriage was recorded in both the Waltham and Lexington vital records, which tells us that Jeremiah was living in Lexington at the time of the wedding while Abigail was from Waltham.
- Waltham record: "KNOWLTON, Jeremiah of Lexington, and Abigail Pierce, Apr. 4, 1771."
- Lexington record: "KNOWLTON, Jeremiah of Lex., m., in Waltham, Abigail Pierce, of Waltham, Apr. 4, 1771."
In March 1773, just two years into their marriage, Jeremiah made a significant investment in the family's future by purchasing three tracts of land from a John White of Charlestown for 77 pounds lawful money. The purchase included a one-acre parcel in Lincoln with a dwelling house and barn, a substantial 40-acre tract of upland and meadow partly in Lincoln and partly in Sudbury, and a 4-acre woodlot in Sudbury. For a young cordwainer (shoemaker) establishing himself in the colony, this was a meaningful commitment to putting down roots.
Together, Jeremiah and Abigail had two daughters in Lincoln:
- Lydia Knowlton, born 16 February 1773, Lincoln; no further record.
- Abigail Knowlton, born 21 January 1774, Lincoln;; married Nathan Gates, 17 June 1790, Westminster; fifteen children; died 28 January 1855, Gardner, Worcester County.
A Family Torn Apart: Abigail's death
Tragedy struck the young Knowlton family in the dead of winter. On 2 February 1776, Abigail (Peirce) Knowlton died in Lincoln at just 25 years of age. The cause is not recorded, but early death in childbirth or from illness was all too common for young colonial women, and she had given birth to little Abigail just two years earlier. The Lincoln town records mark her passing with quiet simplicity:
"Abigail Knowlton, wife of Jeremiah Knowlton, Departed this life February ye 2d A./D. 1776"
The timing could hardly have been worse. The colonies were on the very brink of war — just months earlier, in April 1775, the Battles of Lexington and Concord had been fought practically in Jeremiah's backyard. The Declaration of Independence was still months away. Jeremiah, a young widower, now faced raising at least one small child — two-year-old Abigail — in the middle of a revolution. Jeremiah my have relied on his widowed mother to help raise his daughter during this time.
A Soldier in the Revolution
Jeremiah Knowlton didn't sit out the fight for independence. Despite his domestic hardships — a recent bereavement and a young child at home — he enlisted in the Continental forces at least three times during the Revolutionary War, serving in campaigns from New York to Rhode Island.
In 1776, the same year his wife Abigail died, Jeremiah served as a sergeant in Captain Simon Hunt's company in New York. The following year, 1777, he was at Saratoga — one of the most pivotal battles of the entire war, where General Burgoyne's British forces surrendered to the Americans, convincing France to enter the conflict on the American side. Records show Jeremiah was discharged at Saratoga, having traveled 240 miles from Fort Edward, for which he received a travel allowance. The Lincoln town treasurer's accounts confirm payment to him: seventeen pounds five shillings for his service in both the New York and Saratoga campaigns. The town ledger reads:
A Second Family: Hannah Goffe
On 9 September 1776 — just seven months after Abigail's death, and in the thick of his first military service — Jeremiah married again. His second wife was Hannah Goffe, born around 1750 in Massachusetts Bay Colony, also of Lincoln. The Lincoln town record captures the marriage notice in the clerk's own hand:
Later Life: Land, Loss, and a Final Move
By early 1783, with the war winding down and the peace treaty with Britain on the horizon, Jeremiah began selling off the Lincoln properties he had worked hard to acquire a decade before. In February 1783, he sold one acre of land — including the dwelling house and barn near Miles Bridge — to Seth Badcock, a local housewright, for 90 pounds. Just weeks later, in April 1783, he sold the larger 40-acre parcel of upland and meadow partly in Lincoln and partly in Sudbury to John Lowell Esq. of Boston for 60 pounds. Both deeds were signed by Jeremiah and, interestingly, by a woman named Joanna Knowlton as his wife — suggesting Hannah may have been using a different given name, or possibly indicating a brief period of record uncertainty.
With the Lincoln properties sold, the family very likely relocated to Weston, Middlesex County, the next town over. It was there, on 11 June 1785, that Jeremiah Knowlton died at the age of 40. The Weston vital record notes his passing with a touching detail about what became of his family:
No gravestone or burial site for Jeremiah, Abigail or Hannah has yet been located, and no probate records for his estate have been found in the Middlesex County court records.
Putting It All Together
Jeremiah Knowlton's forty years on earth were shaped by nearly every defining experience of his era. He was born into a farming community in colonial Massachusetts, lost his father young, grew up as the colony's tensions with Britain escalated toward war, worked as a cordwainer (shoemaker), acquired land and started a family, lost his young wife in the same year the Revolution began, remarried and kept farming — and found time to serve in three separate military campaigns, including at the decisive Battle of Saratoga. He died at forty, leaving behind a widow and children who made their way back to Concord to start over.
His first wife Abigail Peirce, who died at just twenty-five, left behind only two daughters — one of whom, also named Abigail, grew up to become the matriarch of a family of fifteen children and lived well into the 1850s. Somewhere in those fifteen Gates children and their descendants, the Knowlton and Peirce lines carry on.
Theirs is a story that belongs very much to its time and place: ordinary people living through extraordinary events, their names recorded in town ledgers and deed books, their stories waiting to be read again.

"June [15th] By Seventeen Pounds five shillings paid Jeremiah Knowlton for his Service in a Campaign at New York in the year 1776 and at Saratoga in the year 1777 — £17 5s 0p"In 1778, Jeremiah enlisted yet again — this time as a private in Captain Francis Brown's company under Colonel McIntosh, serving in General Lovell's brigade in Rhode Island. He enlisted on 1 August 1778 and was discharged on 11 September 1778, a service of one month and fourteen days. Three separate enlistments across three years of active war. Whatever else one might say about Jeremiah Knowlton, he was not a man who shied away from duty.
A Second Family: Hannah Goffe
On 9 September 1776 — just seven months after Abigail's death, and in the thick of his first military service — Jeremiah married again. His second wife was Hannah Goffe, born around 1750 in Massachusetts Bay Colony, also of Lincoln. The Lincoln town record captures the marriage notice in the clerk's own hand:
"Jeremiah Knowlton and Hannah Goffe both of Lincoln their intention of marriage has been published in Lincoln according to Law & a Certificet given.Jeremiah and Hannah would have three sons together, all born and baptized in Lincoln:
Lincoln Sept. the 9th 1776 John Adams Town Clerk"
- James Knowlton (1st), baptized 22 February 1778, Lincoln; died before July 1782, probably in Lincoln.
- Joseph Knowlton, baptized 14 May 1780, Lincoln; no further record.
- James Knowlton (2nd), baptized 28 July 1782, Lincoln; no further record.

"Jeremiah Knowlton, d. June 11, 1785. His widow, Hannah, and family were removed to Concord."Hannah packed up the household and moved the family back to Concord — the very town where Jeremiah had been born forty years earlier; perhaps Hannah and Jeremiah’s daughter moved in with Jeremiah’s mother. Hannah (Goffe) Knowlton outlived her husband by twelve years, dying in Concord on 20 October 1797 at the age of 47.
No gravestone or burial site for Jeremiah, Abigail or Hannah has yet been located, and no probate records for his estate have been found in the Middlesex County court records.
