Looking for relatives or information on Oldenburgs from Wisconsin. The earliest ancestor I have was Friederich Oldenburg married to Charlotte Raatz. They came from Germany and lived in Wisconsin. My line comes from their son Albert. Albert, his wife Anna, and their children Walter, William, George, Max, Kathryn, Hans, and Charlotte all resided in Fond Du Lac, WI at one point or another.
Walter moved to New York and married Florence Schulze, they had a son named Albert Walter.

I am not sure if George ever married but he died in Wenatchee, WA.

William lived in Milwaukee, WI with his wife Loraine Hencke as far as I know they had two sons James and David Lee.

Hans married a woman named Dorothy I believe they stayed in WI.

Kathryn was my Great Grandmother, she married Edward Hennen. Their children were Diane, Dorothy, Darlene, Doris, Donna, Daniel, and Donald. They lived in Fond Du Lac and then moved to Longmont, CO.

Charlotte married Lowell Williams. I know they had at least one daughter named Marilyn.

They resided in Fond Du Lac as well. If anyone is related to any of these Oldenburgs please contact me. Thank you for reading.
