Last January marked the passing of Georgia Harshbarger Geiger, a resident of Monroe, WA. Georgia was the sole surviving daughter of Joseigh Edward and Melissa (Proffitt) Harshbarger. According to the report, she was 107 years old and fully lucid until the end.
Born in Red Lodge, MT in 1901 and reared mostly in Montana, she also lived in California, Oregon, and at last, Washington state.
There is a nice online newspaper article in the Monroe Monitor & Valley News, whose website is probably something like moneroemonitor.com. I found the article by Googling the name Georgia Geiger.
If you know of any surviving kin of this woman, please let me know at email@example.com, as I am (albeit, distant) kin.
