I have been researching for a long time and find very little informationon the Dunhams. There was a name change in the early 1900's. My great grandfather was named Scott Dunham, but did have a wife and children he left in MS. His real father's name was Scott Nelson, a white man of irish or scottish descent in the SE Miss. area. Family traits are red hair, hazel or green eyes. Most of the men are said to be womanizers on the white and black sides of the family. Descendents in the ARK,MI, IL and CA areas now. A large family reunion is planned this summer. Let me know if you are interested, I may have some other info that may help. According to older family members, Katherine Dunham the famous dancer may have been related also.
