I finally got to Prairie Home Cemetery yesterday. Unfortunately, there is no stone for Lucy Winters. I did take pictures around the area where the Prairie Home website says she is buried, and did see the other graves around hers.
I forgot that you had mentioned about Northview Cemetery, though....and I was only about a 1/4 mile from that area. I will try to check it out in the next week or so.
If you would like me to send you the picture I took at Prairie Home Cemetery, send me a message if you can. I can't send you a message because I am not an ancestry member at the moment.
