Pitcher Family Genealogy Forum
Do you know when your ggrandfather, William, died? If you do, you can send for his Death Certificate. It will (usually) list his parents names and his place of birth. My grandfather's DC listed his exact birthplace, Norwich, England. Don't really know what the records in Canada list, though.
Bye the way, my family emmigrated to USA during the same time time period. My gggrandfather, WILLIAM PITCHER, was born in Norwich in 1813. There are several William's listed in the 1850 and 1880 Census for Norwich.
