I've been trying to find out any information regarding my grandfather who was born on Bergen, Norway and immigrated to the United States and then to Canada in the late 1800's or early 1900's. There have been rumors among the family that they changed their name from Anderson to Olson. If so would they just change their name on a whim or would they have to do so legally.
Their names were Andrew Martin born July 22, 1876, my grandfather Olai born 1881 and two sisters whose names I do not know. One of them immigrated with their two brothers and settled in the United States and the other remained in Bergen. I know my grandfather served with the Norwegian Militia. There father is believed to have died at sea. Both my grandfather and my great uncle were farmers here in Canada.
Any information that you can give us or directing us in the right direction would be greatly appreciated.
