was the son of Thomas Endecott of Chagford, Devonshire, and Alice (Westlake?) Endecott, a woman of considerable landed possessions in the parish of Stoke-in-Teignhead.
His grandfather, John Endecott, held large tin-mining interests in the county, and was a man of some wealth. He survived his son Thomas, who died in 1621, and on his own death some fourteen years later practically disinherited the younger John, whose religious convictions had doubtless run counter to his own.
This may serve to explain the fact that in his records and correspondence, the Governor made almost no references to his connections in England.
