Many of the family that came to the United States Dropped the "h" in favor of an easier Sundal "westernized" version.
My Grand father was from Sundahl Norway but changed the spelling to Sundal. He was first born Son in the sons of Norway line, from Sundahl Norway, as I was the first grand son. He had a son, First born, David Sundal, who resides in Grand Junction Colorado.I reside now in Las Vegas NV.Other relatives surviving the lineage are my Mother, Faith James,"Sundal". Photos of Sundahl norway are on the web, and are a far cry from my Grandfathers photos. His family settled in the area and were owners of huge tracs of land. the were very successful in ranching and later shipping.My grand father moved to Wisconson and later to Freeport Il. where he became a Minister, Married, had one daughter. He then was then divorced. He again married, Ruth Edmundson and had three children.
