I have been researching the Gaa side of my family tree for several years now. I have been to Upper Sandusky, Ohio and that area to research my family tree as well as to Hockenheim, Germany and the surrounding area to research the Gaa family back to around 1650. I have heard several times that the Gaa family originated in Scotland and then moved and settled in Germany. Does anyone know if that is correct? I have a trip planned to Scotland for the end of May 2015 and would like to do a bit of research in Edinburgh if time allows. I was hoping that someone could point me in the right direction to help expedite my search in Scotland, for example, does anyone know which part of Scotland the family came from, a town name, any proof, etc? Thanks!!
