I am looking for any information on ancestors of my grandmother, Julia H. Johnson of North Dakota, born around 1886. She was married to Fred Alva Calkins (my grandfather). Her parents were Claus and Laura Johnson who were born in Norway and emigrated to the U.S. in the mid-1800s(?) I can't find anything on this branch of my family (on my mother's side). I found ONE BILLION entries named Johnson, but no Claus who was married to a Laura. I need help! Thank you!
