I'm Stephen Hatton, great, great grandson of Christopher W.C. Hatton.
I'm a part of the Australian side of the family. I have the family tree from John and Sarah in the 1800's but nothing further back than that in Ireland.
My email address is firstname.lastname@example.org if you'd like to chat.
I was on today and saw the address where Sarah passed away, don't think it's the same building though.
