I saw your original post from a local library and sadly didn't have a clue as to what I was doing then!
I now have Internet at home and have spent a lot of time on my family history over the last 5/6 years.
Mark Andrew Rolfe was my paternal great-grandfather. His daughter Bertha Rolfe 1892-1955 was my grandmother and her son George Benjamin Bishop is my father born 1928.
I live in Sussex, England but am more than keen to be in contact with you. I have found lots of relatives in England AND in Australia through this hobby of ours!
My email address is firstname.lastname@example.org
if you wish to respond. I have a photo of Mark Andrew if you are interested.
Hope to hear from you asap
