Anybody out there belong to the MacDonald clan? How do you decide which tartan is your's? My mom-in-law is a first generation american decendent from an immigrant from Scotland born in Aberdeen. I am told that is not an original MacDonald clan territory. She, however, cannot remember her dad's dad's name or where he was born. It was in Scotland somewhere she says. I am trying to put a family tree together before she dies so we don't loose this valuable information. Hope someone can help. Much appreciated.
