My Jordahl, or actually Jordal family came from Norway. My great grandfather Ole (pronounced Olah in Norwegian, not Olee) married my great grandmother Marie (Mary) Jonsdatter Boyum. The Boyum farm, which gave the name to my great grandmother is just up the fjord from the Jordal river valley and farm. Jordal is broken down into Jord (earth or farm) dal (valley).
