Coming to this one 2 years later as it wasn't tagged England, so it didn't come into the England Project feed in 2020. It looks as though C. Mackinnon has created the fifth daughter Margaret today.
If you have a suggestion for a first degree relative of an England Project managed profile, putting a comment on the profile itself will send it to every member of the England Project subscribed to the England Project Google Group (virtually all of them !). Please add details of any primary source you have as evidence.
