The most authoritative account of the family of Isaac Cummings’ of Mistley, Essex, England, and Essex County, Massachusetts, is now that of Plummer275, which supersedes all previous work. The information given here about Isaac’s children is taken from that source. Mooar in his Descendants of Isaac Cummings110 gives details about Isaac Cummings’ property and offices, along with a transcript of his will.

See also the website of the Isaac Cummings Family Association284 which proposes as a result of recent research that John Comyn and Amy Green of Copford (10 miles from Mistley) were the parents of Isaac Cummings.
