Thanks, Billy. I see the Peerage has Macdonalds of Slate. As to breaking them down by Baronetcys, I don't see that. Hopefully someone with knowledge of the Macdonald Baronets will pipe up here and assist. If we don't get a consensus by the end of the week, I'll proceed to create the categories as shown above.
