I have a William M. Flanagan who was born on March 7, 1863 in RussellCo., KY and died Oct. 8, 1947 - his name was William M. but my my father always called him Barney. It was only when I began looking at the records did I learn that his name was really William (there was at least one other William M. - my dad's uncle, who everyone called by his middle name Marcus - which may explain the use of Barney. The William born in 1863 would have been, I think, a first cousin to my greatgrandfather Enoch. However, I don't have a George or John as brothers to him. You can check what I have by going to http://worldconnect.rootsweb.com and searching the database or my individual data at http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?db=flanaganfamily
Hope that this helps.
