Was it your father's father who was a Hill? If yes, then you could be tested for the Hill surname study. If no, then you could get the Y chromosome DNA profile and contribute the results to the Hartigan surname study. Whatever your father's surname was (if you or he were not adopted), that is the Y DNA study you should participate in. You wouldn't want to contribute your Hartigan results to a Hill study - it's apples and oranges. The Hill study compares men with the Hill surname to each other to see which ones are descended from which Hill male ancestor. The Hartigan study would compare your DNA to that of other men who have the Hartigan surname to see if any of them might share a common Hartigan male ancestor with you. If your mother was a Hill, it won't do you any good to participate in the Hill Y chromosome DNA study, because she didn't have one to pass on to you. Women have two X chromosomes, one contributed by their mother and one by their father. Men have an X chromosome from their mother plus a Y chromosome from their fathers. --- Javbst@aol.com wrote: > I support the DNA testing if that can be a useful > tool for research, though I > asked Aaron about Hill DNA testing and in emails to > me he replied that since > I wasnt a Hill it was for only, I also was told that > by one of the testing > labs noted here in the discussion ... yet my great > grandfather was a Hill and my > grandmother a Hill, so I really dont understand the > exclusionary basis of this > testing. > > B Rgds, > Scotty Hartigan > > ------------------------------- > To unsubscribe from the list, please send an email > to HILL-request@rootsweb.com with the word > 'unsubscribe' without the quotes in the subject and > the body of the message >
