English Origenes case studies would have you believe a simple YDNA cheek swab will lead you to you ancestor's genetic homeland. The "GH" is the location where your father’s patrilineal ancestors lived when the first one took your surname some 30 generations ago. For dedicated surname researchers looking for the origin of their surname it means you will have much more time for gardening or a good book. To get a sense of the quality of research behind a typical Origenes report read this critical review of the Chaney case study which concluded the surname was from Northamptonshire and the Chaneys were not Normans but rather ancient Britons. Two words to the wise, caveat emptor. Note: The analysis below contains blue underlined links to maps and distributions which are central to the argument refuting the claim. http://geogenealogy.ca/chaney/text2.htm
