See Delorey847 for further information.

Richardson315 provides further details on his life: John Parker “was a legatee and witness to the 1640 will of John Aylett of Rayleigh, who bequeathed him 20s and called him ‘servant’. John and Mary immigrated to New Engand by 1649, where they settled first at Woburn, and by 1654 were at Billerica, Mass. John Parker was the first town clerk of Billerica, the first collector of taxes, and he built the first meeting house there. He was named a legatee and overseer in the 1659 will of Edward1 Converse of Woburn, Mass., who called him ‘kinsman’ and bequeathed him 40s.”

There is a short paper by Prentiss Glazier on “Chamberlain Families of Early New England”813 that contains many assertions about this Thomas Chamberlain, but provides almost no support for any of them and contains at least one factual error. Glazier asserts that this Thomas Chamberlain was “almost certainly” the son of a Francis Chamberlain of Elizabeth City, Virginia, who emigrated from England in the “Marmaduke” in 1621.814 No evidence for such a relationship is presented. Glazier goes on to assert that this Thomas Chamberlain emigrated from Gravesend to Virginia in “May 1635, aged 20”; this statement appears to refer to the entry in Hotten for a “Tho: Chamberlin,” aged 20, embarked in the “Thomas” on ijo [2nd] June, not May, 1635.815 Glazier further claims this Thomas Chamberlain was one of the party of Puritans who fled Virginia in 1644 with Daniel Gookin, apparently on the grounds that Daniel Gookin and Thomas Chamberlain were made freemen in Boston on the same date, and that Daniel Gookin is listed in Hotten’s Virginia muster rolls shortly after the Francis Chamberlain above. In the absence of further supporting details, most of these connections strike me as speculative.

Savage816 give the date of Thomas Chamberlain’s marriage to Mary (?Pope) Parker as 19 April 1674.
