I have been trying to trace my grandfather for some time, with no success. His name was William Bridson and he left IOM and came to Australia - marrying my grandmother in 1890 in Broken Hill in NSW. I have got a copy of his marriage cert but he has not noted any parents names. I have since been told that he said he had 7 sisters - which could be a line to follow up. We were told that one sister was named Cisily. We have found one William Bridson who had a sister of that name but his christened name was William Caesar, and our grandfather claimed that his name was William Granville. He passed the name Granville on to his eldest child so there seems to be some history there. I was wondering if any of the 7 sisters have families who know of any of this history.
