I am trying to locate where one of my ancestors, William (George?) Mason, who came from and where he landed. The difficulty is he was about 10 or 12 years old and he came by himself about 1828. He appears in the 1851 Census record of New Brunswick , Canada, but not with relatives! It is possible that his parents had died in England (Scotland? or Ireland?). Was this normal for children to leave, England for example, and sail to America (USA or Canada) by themselves? Is so, did someone on board look after them or did they have to look after themselves? What would it have cost in those days to sail from Europe to North America?
