Hi Alan, I just got back to this site today, and read your message. I know the Prater family. I called Sue this evening, and she told me that Ada died in March. She married Bob Prater. Ada and Hazel were full sisters. Sue said there is a sister still living in Minn. She said William was married several times, and there were children from most marriages. She has some things of her mother's and would be happy to share with you. You can either email me direct at email@example.com or send me your mailing address, and I will give it to Sue.
Union Furnace is just a little county village, and everyone there knows everyone else. It is in Starr Township, on State Route 328. Glad to be of help! Kay
