I am beginning to work on my Swan family lineage. I have learned that they came to New York state sometime after the American Revolution. I am want to know how do I determine whether they were Chattan MacQueens or Isle of Skye MacQueens. This determines whether I will be ordering an Isle of Skye kilt or a Chattan kilt in addition to the MacQueen.

The other question is if this is impossible to determine are there any rules regarding which I should wear?
