Please forward a sample of your father's DNA to ... REALLY! How am I supposed to know that? Here's a little exercise you can do if you feel like it. Take a look at the following websites - //scripts.ireland.com/ancestor/surname/index.cfm (Irish surname site) www.spatial-literacy.org (British surname site) On the latter site you'll have to find the surname profiler via the site map. Put the name "Henry" in the search engine on each site and you'll have some useful data to play with. Whether or not you'll be any wiser about your father's ancestry I cannot say.
