I wrote an AI-assisted ABC biography for my 5thy great-grandfather Amos Plimpton, a Revolutionhary War soldier, in ABC Biography of Amos Plimpton and Mary Guild of Massachusetts (1735-1808), based on my genealogical research over 38 years.
I wondered what Amos Plimpton might have told his grandchildren in a life memoir in 1807.

The Life & Remembrances of
Amos Plimpton of Medfield, Massachusetts
1735 – 1808
As told to his grandchildren in the winter of 1807
On My Birth and the Family I Came Into
Come now, draw close to the fire, for the night is cold and I am not as young as once I was. Your grandmother Mary — God rest her — used to say I could talk the bark off an elm tree, and perhaps she was right. But I am seventy-two years old this past June, and if a man cannot speak plainly of his own life to his own grandchildren, then what is the use of living so long?
I was born on the sixteenth day of June, in the year of our Lord 1735, in this very town of Medfield, Suffolk County, Massachusetts Bay Colony. My father was John Plimpton, born in 1708, and my mother was Abigail Fisher, born in 1711. They married here in 1731 and set up housekeeping on this same ground where you sit tonight — ground that the Plimptons have held, and worked, and loved, since before your grandfather's grandfather's time.
My father was a steady, quiet man who kept his fields well and his word better. My mother was a woman of great endurance and practical sense — she outlived my father by nearly thirty years, which tells you something about the constitution of Abigail Fisher. She did not die until 1785, and when she went, I inherited this estate entire, paying out the shares owed to your great-aunt and great-uncle, as was right and proper.
I was the second child, the second son. My elder brother John was born in the winter of 1731 and 1732, a fine strong boy — and then he died in April of 1754, at twenty-two years of age, before Father even passed. That was a hard year, losing both brother and father in such quick succession. After John went, I became the eldest son, and the weight of this land and this name settled upon my shoulders. I have never shrugged it off, nor wished to.
After me came my sister Olive, born in 1737. She married Adam Peters in 1758 and died young in 1768, only thirty-one years old. Then my brother Abner, born about 1742 — a restless soul, Abner, who eventually made his way north to Vermont, where he lives yet, God willing. And youngest of us all was Unity, born about 1746, who married Benjamin Boyden and has lived in Medfield these many years still. Unity has always been the one most like our mother: steady, long-lived, not given to complaint.
On the House and the Land
Some of you have asked me about the old cellar hole behind the barn — the depression in the earth that I showed you last summer. That is where the very first Plimpton house stood in Medfield. Not this house. Not even the house before this one. The original. Older than your great-grandfather, older than his father. When that first house rotted away, as all things must, a second one was built on the spot now occupied by this house — a two-story structure with one great room below and the front door at the westerly end. They added a lean-to in the rear sometime after.
When I married your grandmother Mary in 1800 — that is, when I married your step-grandmother, Mary Breck, God bless her — your parents were still living here with me, and the house had grown too tight for all of us. So we added a new part to the west end, of much the same shape and size as the old part. The whole house became quite respectable, I think.
I have been told that I am the last of the Plimpton name to hold this original homestead. If that is so, I accept it with a full heart. The land passes to you, John, through my will, and I do not grieve the change of name, for the blood is the same. This ground will be tended by my grandchildren and their children, even if they bear a different name, and that is enough for any man.
The land has been my life's work. In 1765 I purchased a fifth-part share of a forty-five acre woodlot in Wrentham — good timber land, bounded on the north by the Charles River — from your great-uncle Abner and his wife Esther, for twelve pounds. I turned it over the same year to a yeoman named David Wight of Medway for twelve pounds and six shillings. That is the way of it: land is not merely a thing to hold, but a thing to work with, to trade in, to make something of. A man who only sits on his land and admires it will soon have no land at all.
On My Marriage to Mary Guild
Now I come to the part of the story that matters most, and I will not rush it.
I was twenty-one years old in December of 1756 — the same year my father died, which gave those months a mingled character of grief and joy that I have never quite forgotten. Your grandmother Mary Guild was born in 1735 in Walpole, the daughter of Nathaniel Guild and his wife Mary Boyden. Walpole is no great distance from Medfield — six miles, perhaps — and the families of those two towns had long been acquainted through trade and marriage and the general commerce of neighboring communities.
Mary was a handsome woman, sensible and kind, and she came from good stock. Her father Nathaniel lived to be eighty-four years of age, which I take as evidence of the constitution of the Guild family. Her mother Mary Boyden died in 1776. Mary had five brothers and sisters: Nathaniel, Mercy, Susanna, Samuel, and little Mehitable, the youngest. They were a close-knit family, as families in this part of the world tend to be.
We were married on the ninth of December, 1756, here in Medfield. The record in the town book says simply: 'Amos Plimpton and Mary Guild, Dec. 9, 1756.' Plain enough. But I tell you, there was nothing plain about that day to me.
We were married forty-four years. Let that number sit with you a moment. Forty-four years. She died on the twentieth of March, 1800, and there is not a morning since that I have not thought of her before I rose from my bed.
On Our Children
God gave us five children, and He saw fit to take three of them back while they were still small. I do not say this with bitterness, for I have seen enough of life to know that the Lord's purposes are not always made plain to us in this world. But neither will I pretend it was easy.
Molly was born on the eighth of May, 1758. She was our first and, for a long while, our great joy. She grew into a capable, warm-hearted woman, just as her mother was. She married Joseph Cole in 1780 and, after his death, your grandfather Amos Kingsbury in 1785. Molly and Amos, and you, John, have lived here with me on this land, and the arrangement has suited us all well enough, though I confess the house has been somewhat crowded from time to time.
Elizabeth came next, born the fourteenth of June, 1761. She was a bright, lively little creature. She died on the second of May, 1766, just before her fifth birthday. Mary and I buried her in the churchyard and carried the grief of it quietly, as one does.
Then John, born the twenty-second of September, 1763 — named for my grandfather, father and my brother, as was right. John died in October of 1765, not yet two years old. To lose a son you have named for your own father is a peculiar sorrow.
In March of 1770, another son was born to us — we called him Amos, after me. He lived two months. He died on the twenty-sixth of May, 1770. Three children dead before they could walk or talk or know us as their parents. Mary bore this with a grace that I could not always match.
And then came Mercy, the mother of you lively Smith grandchildren, born the ninth of September, 1772. She is well named — Mercy she has always been, gentle and steady. She married your father, Aaron Smith in 1795, and I have given her and Aaron the woodlot at Smith's Plane in my will, as well as six hundred dollars to be paid out over six years. It is the least I can do for a daughter who has brought her father nothing but comfort.
On the Revolution
I was thirty-nine years old when the war began. Some of you will think that a great age for soldiering, and perhaps it is. But I tell you that on the nineteenth of April, 1775, no man in Medfield who had the use of his legs stayed home.
The alarm came early in the morning. You have heard the story of Lexington and Concord — how the British Regulars marched out from Boston in the night to seize our powder and arms at Concord, and how the militia of Lexington met them on the green, and shots were fired, and men died. By the time the sun was fully up, the alarm had spread through every town in the county. I marched out with Captain Ephraim Chenery's company, part of Colonel John Smith's regiment. We served eleven days. I will not pretend we won any great glory in those eleven days, but we were there, and that mattered.
After that, I was commissioned Second Lieutenant in Captain Aaron Guild's company — Guild, you notice; an uncle, I believe, of your grandmother's — under Colonel Lemuel Robinson's regiment. We enlisted on the twenty-ninth of January, 1776. The regiment was raised in Suffolk and York counties, and we were sent to Dorchester Heights.
Now I want you to understand what Dorchester Heights meant. General Washington had been in Boston since the previous year, with the British army sitting in the town and the harbor full of their ships. All through the winter, the men had hauled the cannon that Colonel Knox had dragged across two hundred miles of wilderness from Fort Ticonderoga — great iron guns that we had captured from the British the spring before. In the night of the fourth of March, 1776, we moved those cannon to the heights above the harbor.
When the British general woke the next morning and looked up at Dorchester Heights, he saw cannon staring down at him from a position he could not take without great loss. He had two choices: attack and be destroyed, or leave. He left. The seventeenth of March, 1776, the British evacuated Boston. I was there. I saw those ships move out of the harbor. It is not nothing, to see such a thing.
I also served in Captain Sabin Mann's Medfield militia company. I am listed in the records as having paid fifteen pounds in September of 1777 in lieu of further service — a man drafted to complete the Continental quota. By that time I was forty-two years old, with a farm to keep and a family to feed. The law allowed for such payments, and I made mine without shame. I had already marched when others had not.
They call me Lieutenant Plimpton in the town records, and that is what is written on my stone in Vine Lake Cemetery. Lieutenant I was, and Lieutenant I shall remain.
On the Estate of My Father-in-Law
Mary's father, Nathaniel Guild, was a man of property in Walpole, and he lived long enough to see the Revolution won and the new nation established. He died in 1796, at the age of eighty-four. Before he died, in 1795, he made his will and left his estate in seven equal parts among his children. Mary received her seventh share.
In April of 1798, all of us — Mary and I, and Mercy and Ebenezer Hewins, and Susanna and Ezra Morse, and Mehitable Guild, and Samuel Guild of Easton — gathered our names to a deed and sold the Guild lands in Walpole and Sharon and Foxborough to Harman Guild for sixteen hundred and seventy-one dollars and forty-three cents. It was a considerable sum, and the settling of it brought to a close the Guild family's long connection to that Walpole land. Mary and I put our shares to good use here in Medfield.
On the Latter Years and the Loss of Mary
The census-takers came through in 1790 and again in 1800. In 1790, it was just Mary and me, the children grown and gone, the house quieter than it had been since before Molly was born. In 1800, it was me and Molly and her family had come back to live with us, and the house was livelier again.
Mary died on the twentieth of March, 1800. She had been my wife since I was twenty-one years old. She had buried three children without ever losing her steadiness. She had kept this house, kept this family, kept me — and I will not pretend that I was always easy to keep. She died in the spring, which I think she would have chosen if she could, for she loved the spring — the first snowdrops, the smell of the earth waking up.
I married again in November of 1800. Her name is Mary too — Mary Pratt, widow of Elijah Breck, from Sherborn. She was fifty years old when we married, fifteen years younger than I, and she has been a good and faithful companion to me in my old age. When she came to live here, Amos Kingsbury was still in the house, and we found it rather close quarters, which is why we added the new part to the west end. Two Marys I have had, and both of them better women than I deserved.
On the Writing of My Will
I wrote my will on the thirteenth of January of this year, 1807. I am seventy-one years old and in reasonable health for a man who has soldiered and farmed and buried children and outlived a wife. But I am not a fool, and a man who reaches my age without putting his affairs in order is a man who does not love his family.
I have left the house and land to you, John Kingsbury — my grandson, Molly's son. You are the one who has worked this ground beside me, and you are the one I trust to keep it. You will take possession of the house at my death, and of the rest of the land at your mother's death. In the meantime, I have asked you to provide for your step-grandmother Mary Breck: firewood and corn and rye and cider and pork and beef and cheese and butter and flax and wool, every year, as long as she remains my widow. That is not a small thing I ask of you, but I believe you are equal to it.
To your Aunt Mercy and her husband Aaron Smith, I have given the woodlot at Smith's Plane, and six hundred dollars to be paid out at one hundred dollars a year. Mercy has never asked me for anything in her life. It is time I gave her something without her asking.
The farming tools are yours, John. The wearing apparel goes to Aaron Smith. The remaining personal estate is divided equally among Amos Kingsbury, Aaron Smith, and yourself. I have tried to be fair. Whether I have succeeded, you will judge better than I can.
On What I Would Have You Remember
You are young yet, the lot of you. You cannot see from where you stand what your lives will become. I could not see it either, at your age. I was a farmer's second son in a small Massachusetts town, and I could not have told you that I would live to see a revolution, to stand on Dorchester Heights and watch the British fleet sail out of Boston harbor, to bury three children and a wife of forty-four years, and then to sit here by this fire and speak to grandchildren about it all.
What I know is this: the land endures. This ground beneath your feet has been Plimpton ground — your ground, in blood if not in name — for longer than any of us can easily reckon. Work it well. Do not be idle. Pay your debts. Keep your word. Marry someone of good character, for you will see that character in the daily round of years, long after beauty and youth have altered.
Serve your country when it calls you. It will call you, as it called me, and you must answer. But come home again. This is where you belong.
I am an old man now, and I have been given to understand by my body that I shall not always be so particular about when and where I sit down. My joints inform me of the weather, which is perhaps the only weather forecasting I have ever found reliable. I am not afraid of what is coming. The stone is already cut, out there in Vine Lake Cemetery, and the verse chosen. I have made my peace with God and with this town and with the long line of Plimptons who kept this land before me.
But tonight I am warm, and the fire is good, and you are here. That is enough. That is, in truth, everything.
— Amos Plimpton, Medfield, Massachusetts, January 1807
