Would you believe this???? I have the Robert jnr in my family tree!!!! He married a Louisa Brooks, whos mother was an ABBOTT, and that is the family name that I'm researching.
Have a look at my tree that I have and you can see the connection.
When you get to the page, request an invite, and I'll let you in.
