I actually got online to try and find out what Brodersen means. The closest I can come up with is "brother son" which doesn't make a lot of sense unless it's "brother's son." I am also, however, interested in learning my geneology. All I know is my dad is David John Brodersen, born 11.21.57, my grandparents are Kathrynne and Paul Brodersen. I don't know when they were born. I can find out my grandma Freda's last name, but I'm not sure how much beyond that. If anyone who knows about my lineage, I'd be happy to hear from you.
