Lydia, That is correct. It has to be his surname. Do you know of any Thorn's that would test? -----Original Message----- From: Lydia Kedzierski [mailto:lkedzierski@yahoo.com] Sent: Thursday, June 01, 2006 9:16 AM To: THORN-L@rootsweb.com Subject: Re: DNA Testing The Thorn in my family history was my father's grandmother (so a Thorn female is my father's grandmother).. My father does not have direct male to male Thorn descendency. Is the only line that the DNA test would work for the line that is my dad's surname (not Thorn)? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
