My grandfather was married for a short time to Susie Hafner and they lived across the road from us when we were kids. They were divorced and we never saw her again, but I know she has family. I have met some of her grand kids. I can find a gravestone in St Michaels Cemetery in Sioux Falls, SD, USA, but I don't know if that's the right person because there is a similar name (different birthdates) in Texas. Can anyone verify or validate? I would like to get accurate birth/death dates and marriage dates. I met some of her grandchildren and would like to contact them again. I believe they were from Illinois or Indiana, but I think Illinois.
