Hi Larry, you did say any information would be welcome. You gain information from a Y-DNA test. Ultimately we are all from "out of Africa", just that we left at different times. Your Y-DNA would tell you something about that journey via the Cain line. An mtDNA test would do the same for your maternal line.
Most of the folks in the Cain DNA project have Y-DNA associated with European origins, but African-Americans are also turning to DNA. Check both the general website www.familytreedna.com and the Cain DNA projects own page www.familytreedna.com/public/Cain-Caine
