Isaac Doty, the fifth son and seventh child of Edward Doty and Faith Clarke, was born at Plymouth, [February 8, 1647/8], the date being entered on the colony record.
At the death of his father, [Isaac] was but six years of age, and probably continued to live with his mother until about the time of her marriage to John Phillips, in 1667. It is somewhat doubtful where he spent the next five years of his life, but It is probable that it was in Sandwich, Mass., where his brother Joseph was also, early in life, a resident. But it is possible that he may have visited in this period Oyster Bay on Long Island where he subsequently lived. An entry on the county records at Plymouth, dated July 5, 1672, shows that "Isaac Dotey, alias Doughty, sells to John Smith, his share of the land willed to him by his father, Edward Dotey.
At a town meeting held at Oyster Bay, January 22, 1672-3, a piece of land for a house lot was allotted to Isaac Dottie. And on February 19 following, sixteen acres were allotted to James Townsend and Isaac Dottie.
Apparently it was a beautiful location to build a house, and Isaac probably married Elizabeth England about this time, based on the likely birth date of their first son, Issac.
It may be possible to confirm family relationships with Isaac by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
