Those of us researching this family still have many mysteries to unfold. One of the legends is that we come from Nottinghamshire. Several trips to England have gleaned information.Deacon John Dunham of Plymouth is probably not the Ralph Denman/Thomas Wentworth line. A researcher has placed the marriage of John and Susanna Keno in Bedfordshire which holds promise, since Clophill-Cainhoe was owned by Roger DaKenney and the parish records exists. Certainly the Dunham-Donham-Denham-Dynhams were in Devon as well as Nottinghamshire but appear to have spread to Bedfordshire, Cambridgeshire , Norfolk and other surrounding counties. Bedfordshire is home to many who came to America in the 1600's. Many family names are what the call place names, deriving from a place and I have found the Dunhams (persons) in written records ca. 1100-1200. There appears, however, to be few if any at Dunham-on-Trent. The different spellings of the name probably came in the pronounciation and Dunham-Donham more closely pronounced than Dynham-Dinham-Denham; sometimes even written Dunnam, Downham and so referenced. Rev. Thomas Denham of Rye, NY wrote his name both Dunham and Denham; Nathaniel Donham of Clermont co. OH wrote his name both Donham and Dunham.Have more.
