Not all cemetery listings are correct. I was in IA several years ago & did some cemetery research. I found a cemetery index that listed my gg grf, but couldn't find anything about his wife. My brother & I went out to the cemetery to at least get a photo of his grave (I am from Oregon, so don't get to IA) and found his wife was buried next to him. It must have been a woops. We are only human and can make mistakes. I was just delighted to find her as well. - Delores
