Thanks for responding. This is not a part of the extended family that I have much knowledge about, and anything which you know will be most helpful. Thank you. As I think I mentioned, I only stumbled across the initial information from the one source, and as far as I know the family is not connected to my own - but who knows. It may be that we have not yet found the connection.
If you would prefer, please contact me directly at firstname.lastname@example.org
