There is this really neat website that helps you figure out what your family's tartan is. Click here to go to the link. I was actually surprised to find that my maiden name did not show up as it's own clan - shows how much I know! It did come up as being part of the MacPherson clan. (by-the-way - I am not planning on sharing my maiden name here but I can assure you it is nothing at all similar to MacPherson!!!! ::grin::)
This is what came up as the regular tartan for the MacPherson clan. You could also check out other versions (dress, casual, pipers, etc.) I found it interesting how they were all such different patterns & seemingly colors.
For the fun of it, I also did my married name which isn't such a secret here (Berry). Again, that didn't come up in and of itself (which I wasn't as surprised about). It did come up as being part of the Forbes clan. This tartan was the default for that clan.
Neat challenge, Dorothy!
