'John, supposed to have been her youngest child, was in 1636, when the settlers removed from Cambridge to Hartford, nine years old, Martha, about eleven, and Mary, probably thirteen.'
'Martha Betts, second daughter, so far as appears, of John and Mary Betts, was born in England about 1625. She married, Jan. 16, 1655, Nathaniel Graves of Wethersfield, son of Thomas and Sarah Graves of Hartford and Hadley, born in England in 1629. ... The deaths of himself and wife, as recorded in Wethersfield, are : "Nathaniel Graves, Sen. aged about 53 died Sept. 28, 1682." "Widow Martha Graves deceased Apr. 13, 1701, ... a 75, as some think." '
Two deeds of gift from John Betts of Wethersfield in 1662, which give "one half of my moveables about my house" to each of "my kinsfolke the children of my Brother Borman" and "my brother Nathaniell Graves" identify the wives of Samuel Boreman and Nathaniel Graves (whose wife was Martha) as the sisters of John Betts, and daughters of "the Widow Mary Betts, one of the first settlers of Hartford."
