The Donahoos lived in Afton (Ottawa County), Oklahoma in the early part of the 1900s.

Ollie Aldace Donahoo was a dear friend of my grandmother's; I hadn't grasped how dear until I found in going through some of her things. I have a photograph of her three daughters, Aldace, Helen, and Kathryn. My mother had added a note to the pic that they were the daughters of Dr. Joe Donohoo (He had the first automobile in Afton). I also have a clipping Grandmother had saved of the obituary for Ollie Aldace Donohoo (the doctor's wife). It's undated, but notes she was a "pioneer Oklahoman and a resident of Tulsa for 39 years.
I hate to pitch these without first making an effort to see if any of her descendants might like to have these items.
