A name, not a pedigree

This is where the name came from, which is not the same as where you came from. Names were translated, anglicised, taken on by tenants and neighbours, and carried in by settlers who were no relation to the family that started them. To follow your own line, the 1901 and 1911 censuses are free and searchable, and give the county each person was born in.
