I have concluded that Jadwin is the son of John and Elizabeth since John had four brothers: Philip, Thomas, Samuel., and Nehemiah. Philip and Thomas' wills do not mention a son Jadwin. John's will has not been found, nor Nehemiah's. Either that or he is the son of Thomas and Hannah mentioned in Elizabeth (Rodway) Jadwyn's will, or a great grandchild of Thomas & Hannah (Jadwyn). The only mention I've seen of a Jadwin Dunscombe (cited as "Downscombe") in Bermuda is in the document "Association Oath Rolls : British Plantations, 1696. Bermuda als Somer Islands in America" from http://www.rootsweb.com/~bmuwgw/oathrolls.html.
