Ignore the post above, the information is incorrect! After further digging I think I have finally pieced some of this puzzle together.
Frank Ockenfels immigrated with his wife Mary (maiden unknown) in 1866 to Detroit, Michigan. They had four children, Mary, Frank, Annie, Joseph.
Joseph went on to marry Helen (maiden unknown) and had at least two children, possibly more but I could not find records on this. Two sons named Frank and Marvin.
Frank then went on to marry Anna (maiden uknown, remarried as Anna Novak, passed away in 2001), who was my great grandmother. They had two sons, Benedict and Marvin. They divorced and I've been told that Frank later remarried and started another family elsewhere.
Benedict married Gloria Kozar, having four children, Theresa, Lauren, Paul, and Trina. Paul is my father.
I believe this information is correct, as there are no other records of a line of Ockenfels living in Detroit at this time period, or since.
If anyone has any information about my family or believe they may be related, please contact me at firstname.lastname@example.org
