I just stumbled upon this board and it is great to see so many Illgens -- Including my brother Steve who posted the message from Tennessee.
I would be interested in reading more about our ancestry. My research skills are lacking however I did stumble across an auto race in California called "The Illgen Classic." I believe it is hosted by the Sports Car Club of America (SCCA). I would be interested in learning more about the history of this event. Or if any other Illgen simply wants to compare notes drop me a line.
