What a puzzle....
I have since learned through an obit. that Wm. was indeed married to Nancy J. Bahall. They also had a daughter. I found a census where Nancy had remarried and Albert, John and Rachael (born in 1875) were living w/ Nancy's second husband (Leander Mantle). The obit. mentioned the two boys, the youngest 5 daughters and Rachael (Mrs. Owens)....but no mention of Sarah.

The obit. states that Wm. married Alice Winkler in 1882 but Sarah was reported to be born June 21, 1880. I have also obtained a photo of the 6 younger girls...Sarah has dark curly hair and a slightly darker complexion and the younger 5 have straight blonde hair and are fairer. I wonder if there was a wife between Nancy and Alice.

Wm. later married Julia Blackwell in 1913 after Alice's death (1891).
