It seems to be established that it was Lydia Penniman and not Lydia Rockwood who married Edward Adams, son of Henry. Here is a recent article on the Pennimans: See Clifford L. Stott, "The English Origins of James1 Penniman of Boston and Braintree, Massacuhsetts," TAG71 (1996) 12-18. See also George Wallace Penniman, The Penniman Family, 1631-1900 (Baltimore: Gateway Press, 1981) and The Penniman Family to 1980, ed. G.D. Penniman (Baltimore: Gateway, 1987). Some who are descended from Edward and Lydia may be interested to know that Lydia Eliot, the wife of James Penniman, was a sister of Rev. John Eliot, the famous "Apostle to the Indians," one of the great figures of the first generation of New Englanders.
