James was born about 1624 in England, He is probably not the son of Edward Doty as Edward came to the colony as a youth. (So, his children would have been born in the new world.) (Consider: Edward Doty (Father) and Winifred Warner (Mother).)
According to Deane, he "was early in this town [Scituate], having married Lydia, daughter of Humphrey Turner 15 Aug. 1649. They had between 1650 and 1670 the following children:
He was a soldier in Philip's war, and 1678, was paid by the Town for nine week's campaign in 1676. This family may have removed to Connecticut." 
The claim by Frank A. Randall, Randall and Allied Families, (Chicago, 1943, p. 4), that the James Doty who married Lydia Turner was a son of Edward Doty of the Mayflower is clearly invalid. He did not share in Edward Doty's estate even though he was living at that time.
