Stephanie,
I've been inquiring into Kihlstrom/Kilstrom family history recently -- you may want to take a look at the related messages on genealogy.com:
http://genforum.genealogy.com/norway/messages/5560.htmlThere are good links in this message to get you going on Swedish Kihlstrom Family Research.
I have cousins that I've met in Norway. Our great-grandparents came to Norway from Sweden in the 1880's. My grandfather (Joseph Valfred Kilstrom, born 2Apr1903) came to the US in about 1920. One of his brothers (Joseph was the youngest) went to Australia -- I don't know which one.
Let's keep in touch. There is a Kihlstrom/Kilstrom family organization in Arizona (USA) doing quite a lot of research. I've corresponded with quite a few members of this family in the US and in Sweden over the years....
