Its because of a DNA brickwall i have, my family mostley come from the uk, ie England etc yet i have on one side of my grandfathers side a lot of matches and in this they go back a very long time in the USA, now the mother of my grandfather and her life is well documented etc and she never left the UK, there is Fulwood barracks in preston where she lived in the 1880s until about 1900, her name is recorded as being a family member to her brother in law in about 1895/96 when he was in barracks at fleetwood, so both places are of some interest at the moment, the only thing i can think of is that who ever was the bio father of my grandfather was from the USA and met her in Lancashire/Preston or fleetwood etc.
