When I started to look for her, I kept finding weird inconsistencies. She appears in the 1910 census living with her husband and 3 of her children, her youngest, Oakley was 15. In 1920, she is living with her daughter Celia and it says she is a married. She is no longer living with Celia in 1930 and I can't find her with any of her other children. There is an obit for her in 1936 several counties away. Meanwhile, I can't find William Henry in 1920 and he gets hit by a car in 1926 and dies in the hospital. His son signs the death certificate and says that William was a widower when Nancy is still alive, living in eastern Ohio, for another 10 years.
As you can see in the photo she was a tiny thing and I presume from the black glasses she was blind. I have no idea why she and William were living apart. Maybe Celia was helping care for her. Could her son really have had no idea that his mother was still alive?
This is what makes family history so fascinating.
