Interestingly I saw your post in my email but I don't see it in the thread!!!???

Anyway, the spellings will be significant, so maybe you want to do some more research on those. However, just because your ancestors came from Scotland doesn't mean they were members of a specific clan. The source I used (very quickly) was this one: http://www.chebucto.ns.ca/heritage/F...Sept_Clan.html

But look around, there may be better sources to be found.
