Looking for male descendants of Samuel Lafayette Dunegan

I'm looking for any direct male descendants of Samuel Lafayette Dunegan (1855 KY - 1936 OK) who either have or would be willing to take a Y-DNA test. I'm hoping to narrow down the branch of Dunegans from which I descend.

Samuel was married to Nancy Catherine Smith and had the following children: William Henry, Samuel Harrison, Mary Ellen, Martin R., Charlie T., Sarah Elizabeth, Homer Bert, Rebecca Ann, and Rosie A. Dunegan

I have had one male cousin take this test for me but we need another male direct descendant of Samuel Lafeyette Dunegan to test for us so that we can compare results and hopefully narrow down the correct branch of the family and allow our research to move forward and be more productive.

Please contact me if you are willing to discuss either through a reply to this query or directly at ladee_bug02@yahoo.com.

Thank you,
Sharon
