Two brothers, Nathaniel and Benjamin Sanborn, named in the Kingstown Charter of 1694 were sons of Lt. John Sanborn, eldest of the three grandsons of Rev. Stephen Bachiler who arrived in America with him in 1632 and came to Hampton, NH in 1638. Another brother, Captain Jonathan, and two sons of a fourth brother, John, must be included with the first Sanborns in Kingston.
Benjamin Sanborn, a church deacon, remained in Hampton Falls and no immediate descendents came to Kingston. Nathaniel Sanborn, although Town Clerk of Kingston in 1695, apparently kept his home in Hampton Falls where his nine sons were born between 1693 and 1719. They spread later to Kensington, Epping, and Chester, but not to Kingston.
Capt. Jonathan Sanborn (1672-1741) seems to have been the real pioneer of the family, ably seconded by two sons and two nephews. Born in 1692, he was an Indian fighter before coming to Kingston where his fifth child, Jonathan, was born in 1700 and followed by seven more. He knew the ways of the world enough to operate the first tavern licensed in the town (1706). He owned much land and became a grantee of Chester.
Capt. Jonathan's nephews, John and Tristram (sons of John), were also Indian fighters and 10 to 15 years older than his sons, who belong in Kingston's second generation.
John Sanborn (1683-1732) married a Fifield in Hampton Falls in 1707 before coming to Kingston where five children were born from 1710 to 1721. (His older sister, Mary, married Ebenezer Stevens and lived in Kingston.) This John later became a proprietor of Chichester.
Ensign Tristram Sanborn (1684-1771). Being only 12 years younger than his uncle, Capt. Jonathan, Tristram seems to have been the most prominent of the early Sanborns. In 1707, at the age of 23, he was on the committee to build the first church on the Plains. He married Margaret Taylor of Exeter in 1711 and had 9 children between 1713 and 1733 of who four died in infancy. Tristram is believed to have built a garrison house after his first home was burned by the Indians - probably on the Exeter road. He was selectman in 1725, representative in 1734, and a deacon for some 30 years. At 87 he outlived his brother John and his two cousins who shared some 50 pioneer years in Kingston together. Five sons outlived him and most of the later Kingston Sanborns are his descendents.
Captain Jonathan's line continued with two sons, Samuel and Jonathan. Samuel served in his father's company in 1724 and again at Louisberg in 1745. Jonathan (Jr.) lived in Kingston and married his first cousin Theodate (daughter of Deacon Benjamin). Samuel's only son, Benjamin, a cordwainer, and his four sons all left Kingston. Jonathan (Jr.) had only one son who left male descendents in Kingston - Benjamin (1720-1794) - whose two sons David and John Q. remained in the Town.
Kingston's first John Sanborn had two sons Tristram and Paul but only Paul's sons, Jonathan and Paul (Jr.) remained in town. The latter fought in the Revolution.
Ensign Tristram had 5 sons. Peter (a representative in the 1775 Congress who lived to be a vigorous 97), Abraham, Tristram (Jr.). His son John had 6 sons including Deacon Jacob Hooke Sanborn (the innkeeper who gave the present site of the First Congregational Church), Captain John (East Kingston tanner whose house still stands, off Willow Road), and Moses ("Tanner Moses" - whose only son endowed Sanborn Seminary).
The early Sanborn family genealogy is fully recorded in a book by Victor C. Sanborn, published in 1899. Late branches of the family are easily traceable since that date.
