John Vassall had two sons, Samuel and William. Samuel was one of the original patentees of lands in Massachusetts in 1628. His monument in King's Chapel, Boston, erected by Florentinus Vassall, his great grandson, in 1766, sets forth that he was "a steady and undaunted asserter of the liberties of England in 1628, he was the first who boldly refused to submit to the tax of tonnage and poundage, an unconstitutional claim of the crown arbitrarily imposed for which to the ruin of his family, his goods were seized and his person imprisoned by the star chamber court, the Parliament in July, 1641, voted him £10,445:12:2 for his damages, and resolved that he should be further considered for his personal sufferings."

His name headed the subscription list to raise money against the rebels in Ireland, and his whole life was indicative of the energy and liberality which characterized many of his descendants.

His son, William Vassall, born about 1590, was the first of his name who came to America. He was an assistant in the Massachusetts Bay Company and one of the original patentees of New England. In June, 1635, he embarked with his wife and six children on board the Blessing, for New England. He undoubtedly settled at first in Roxbury, for in the church record of that town is the following entry: "Mrs. Anna Vassaile, the wife of Mr. William Vassaile. Her husband brought five children to this land, Judith, Frances, John, Margaret, Mary." Also one other, Anne, who afterwards married Nicolas Ware.

William Vassall removed later to Scituate, where he proved himself to be an ever staunch Episcopalian. The Puritans had strong suspicion of him always as "inclining to the Bishops." While he lived in Scituate he was regarded as a highly respectable citizen and of "a busy and factious spirit." He was proprietor of a large estate, which bore the name of Newland. In 1646 he sailed to England for the redress of wrongs in the government and never returned, but in 1648 removed to Barbados and resided in the parish of St. Michael, where he died in 1655, aged 65 years. He bequeathed to his son John one-third of his real estate and the remainder to his five daughters. His Scituate estate consisted of about 120 acres, with house, barns, and the privilege of "making an oyster bed in North River," before his house. The estate was conveyed by Joshua Hubbard to John Cushen and Mathyas Briggs for £120.

His daughter Judith married Resolved White, the eldest brother of Peregrine White, at Scituate, 1640. Frances married James Adams at Marshfield 1646. Ann married Nicholas Ware of Virginia. Margaret married Joshua Hubbard of Scituate. Mary was unmarried and alive at Barbados in 1655.

John Vassall, only son of William Vassall, born about 1625. In 1643 his name is on the militia roll of Scituate, and later bore the rank of captain. In 1652 he sold his house in Boston for £59. In 1661 he sold his Scituate estates and removed, it is supposed, to Cape Fear, N. C, and later to the West Indies.

John Vassall, the only son of Samuel, whose monument is in King's Chapel, married Ann, the daughter of John Lewis, an English resident of Geno. He went to Jamaica shortly after it was taken in 1655, and laid the foundation of the great estate which his posterity enjoyed until the emancipation in 1834. He had two sons, William and Leonard, from whom descended all of the name of which there is any subsequent record.

Leonard Vassall, son of said William, was born in Jamaica, 1678, and was twice married. His first wife was Ruth Gale, of Jamaica by whom he had seventeen children. She died in Boston in 1733. His second wife was widow Phebe Goss, by whom he had one daughter. He removed to Boston previous to 1723. He was early connected with Christ Church. In 1730 he was instrumental in founding Trinity church. The original building was built on land which he had purchased of William Speakman, baker, 1728, for £450. The lot covered by the church was bounded by Seven-starr Lane (Summer street), 86 feet and 169 feet on Bishop's Lane (Hawley street), and is nearly opposite the estate which he purchased in 1727 of Simeon Stoddard, and where he resided until his death. He had large and valuable estates in Braintree and Jamaica.

John and William Vassall, two of Major Leonard's sons, were important men in Boston, and added much to the prosperity of the town.

John Vassall, the elder brother of William, was born in the West Indies Sept. 7, 1713, and graduated from Harvard college in 1732. In 1734 he married Elizabeth, the daughter of Lieut. Gov. Spencer Phips by whom he had four children, and later he married Lucy, the daughter of Jonathan Barren of Chelmsford by whom he had one child. He resided in Cambridge most of his life and died there November 27, 1747. December 30, 1741, John Vassall conveyed to his brother Henry (a planter who had married Penelope the daughter of Isaac Royal of Antigua), in consideration of £9050 over seven acres of land in Cambridge, with dwelling house, barn and outhouses. During the Revolution, no doubt, this house was the headquarters of the Surgeon-General and perhaps a hospital. Dr. Benjamin Church, after he was detected in correspondence with the enemy, was arrested here and confined to his quarters until trial, and left a record of his occupation of the house by his name, cut with a penknife on one of the doors of his chamber, which is still legible though since covered with several coats of paint.
