So if I am reading all of this right...........

I can choose the Fraser Tartan since the name Simpson is a Sept

or

I can choose the Gordon Tartan since Gordon is my Great Great Grandmothers maiden name

or

I can choose the US Navy Tartan since I was in the Navy.

That just makes it more difficult to choose which one to get first since I like them all, but at least I won't feel obligated to get the Fraser first.
