I guess I am very lucky to be able to trace my ancestry back to Duncan I. My ancestors arrived on North American shores to settle Jamestowne VA in 1607-10. I trace my ancestory back 400 years. Col George Reade arrived ca 1630. Through him I go back to Duncan I. Many of my Great Grandfathers were Celts (Scotland, Wales amd Ireland). My question is how Scottish do you have to be to belong to a clan. My father is 100% German but my mothers side is mostly Celtic and English. Walker and Russell are maternal surnames but I cannot prove either back to Scotland but have very strong suspicions. The "Bruce" was my second cousin. My ? Great Grandfather (his second cousin-Fought for England) was killed in the battle that brought him great fame.
