Susan, thank you for your reply. Since posting this query, I found on the 1930 census: John Fischer(head), Elizabeth Fischer (wife), Cwith children: John, Ruth, Elizabeth, Jean Fischer and Dorothy E. Hart(step-daughter). Dorothy Hart was born abt. 1917. I concluded that Elizabeth must have been married before, but was unable to find any reference to that fact other than the child listed as a step-daughter. Your reply has filled in several blanks for me. Thank you so very much.
