hi! Not sure if you have found the burial sites you were looking for yet, but I thought I'd help you out just in case. I have pictures of Oscar's, Hazel's and Vaunden's burial sites. They are at the Swedish Cemetery in Shickley, NE. I don't have any other information except for the pictures... I was at the cemetery in 2005 researching some of my family that is buried there, and ended up taking pictures of almost all the "nelson" gravesites... just in case I found out later that they were somehow related to me. When I just read your message, the names rang a bell, so I went searching and there they were! Please let me know if you'd like them, and your email address so that I can send them. Thanks!!
