I am looking for information on Robert Copeland (1793-1869) and Thomas Copeland (1748-1822) who were both buried in Dixon's Cemetery, Chinguacousy Twp. They both appeared to be living in Etobicoke in 1819. They were probably living closer to Hamilton during the War of 1812. Thomas was living in Toronto Twp. in 1808. They both served in the 2nd York Militia during the War of 1812 along with Jonathan Copeland. I have a number of records for these three men but no family history at this time. What was their relationship to each other?
