Hi Yvonne, I have information on the Coltrain family. It would be nice to share what we have. I believe that Alfred M (Major) is the son of Washington Coltrain and Temperance Jones of Martin Co, NC. He was the eldest son.His siblings names were Elizabeth Caroline, Sarah Jane, Mary Emily, John Washington, Bryant. I have a will for Washington Coltrain which I would be willing to send to you. I can't help you with the possible Indian portion of your family. I have mainly used census records to follow the Coltrain family.
