I am still looking for my husbands father or the family. The only new information I have found is that he worked at the Stockyards in Chicago, and he died there. He had a sister that lived close by with her husband and her husband also worked at the Stockyards. If I have the right sister her name was Doris Miller, no name for her husband though. I was told that he was married to my husband's mother only about five years, and when she moved back to Oklahoma he had already remarried, and had at least one more child a girl. I found out some more information, but it is real personal, so anyone that thinks they may know this Frank Knapp please contact me, and we can discuss it and the personal information can be talked about in private. I thank any and all who have been and is helping me, this is important to my husband. Thank you all very much. Tina Knapp
