I live in Seattle WA, am a member of the Sons of Norway, and Nordic Heritage Museum. It's very possible that your Jorgensen's lived in the Scandinavian community of Ballard (north of Seattle, later annexed to Seattle). I can check with those organizations to see if they have any record of your Jorgensen's. Any additional information would be helpful!
Also, I get downtown to our Seattle Public Library to do research in their Genealogy section, about once a month. I'll be glad to do a look-up for you.
