This page researches the family trees of the Radloff, Trometer, Jeys, Thompson, Kopacs and Dalpez families, and whomever else seems to fit in there somewhere.
If you look at the family tree below (InterneTree), you'll notice it starts with a random individual. To change the "starting point" to another person, simply go to the pull-down menu at the top left and choose "Search for Individual." Find the person you're interested in and designate them the "Primary Individual." Once you do that, the tree will look a lot more interesting!
If anyone spots any errors or omissions, please let me know! I'm trying to keep this as accurate as possible, but errors do sneak in from time to time...
