Hello Lesli, I have just read your message and am interested in whether you received any responses to your question.I realize it has been some time since you first posted it.
I am related to Hiram Wanzer, one of Chicago's early physicians, and the second son of Nicholas and Betsey (Hill) Wanzer.Hiram's first wife was Francis B. Wheeler, with whom he had his only child Mary Ella Wanzer (Jeune). Mary Ella was my grandfather's mother.
The Sidney you referred to was the fifth son in the family, Hiram's younger brother. This Sidney had four sons, and a daughter Bessie Wanzer Peterson born 1867 in Chicago.Your Bertha is probably Bessie.
I am very interested in obtaining any photos, since I have none of this side of the family.The Wanzer Family was a very prominent family in Chicago and someone must have the family photographs.
