My Uncle Steve Wessels – who I alternately blame and thank for my obsession with technology – several years ago (15 or so, it appears) worked extensively to compile a comprehensive listing of the Wessels family tree, including birth dates and dates of death, for just about everyone going all the back to Germany for several generations.
It took a lot of work, is still ongoing and will forever be a gift to the whole family. Thanks, Steve. Pretty darn cool.
Side note: Steve is the original tech guy in our family. He makes his living doing it, introduced me to my first computer (an Apple Macintosh in 1984) and has since fascinated me with his wide breadth of knowledge on all sorts of sciences. Follow him on Twitter for all sorts of interesting tidbits about all sorts of things, but mostly tech and other sciences.
