Lydia, If your dad is a Thorn male he carries the y chromosome that is used in DNA. Y chromosome follows the males from father to son down . Yes , it would be great to have him test to compare to the other New York Thorn's that have tested. It helps to bring clans (groups) together and helps further research . -----Original Message----- From: Lydia Kedzierski [mailto:lkedzierski@yahoo.com] Sent: Wednesday, May 31, 2006 9:33 AM To: THORN-L@rootsweb.com Subject: DNA testing? I am a Thorn descendent but off of a female Thorn a few generations back. Is their any value to asking my dad to be tested? We are descended from Orange County, NY area Thorn/Thornes. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
