Their is a book out on the Davis and Coltrane Family in Randolph Co., NC. You can also found this book at the High Point Library in the North Carolina Room. I just got my book last year from my husband cousin who is a Coltrane. Alot of the Coltrane that I have found so far are located in Guilford and Randolph Co., NC. The one that my husband follow is buried at Centre Friends Ch. Cem. in Guilford Co., NC who is Lindsay Coltrane who married Margaret Hodgin both of them are in Centre Friends Ch Cem. His father William Coltrane who married Sarah Frazier are at Marlboro Friends Ch. Cem. Will be happy to help any who is from this line.
