Are you still looking for information about the Frohock's in Southern IL? This is the best history I've come across so far for the Frohocks in IL. http://members.cox.net/frohock2/black.htmlhttp://members.cox.net/frohock2/black.html. I have noticed some things for my ancester, John S. Frohock, don't add up, but I'm still trying to work that all out. I'm very grateful to J. Robert Black for his efforts in creating his history so thoroughly & accurately, and for sharing his work.
