I am trying to trace the birth record for Conway James George Williams. He was born on the 10th September 1826 in Guernsey. According to his death record from St Malo, France, his parents were George and Margaret (O'Connor). I have always thought he was born in Ireland but his death record states he was born in Guernsey. Perhaps George & Margaret were also married there but I have no idea how to search for Guernsey records (I live in Australia). I am rather certain that Conway also had a brother, William Henry Williams who was born about 1811.
Any help would be most appreciated
