Hi, this is really kind of you. They mostly lived in Libertyville, they owned farms for racehorses. It would have been close to the Lake Co. Fairgrounds, I think. There is one listing that I have that says that they lived on the pike from Chicago to Libertyville. I doubt this is any help. Surnames: McMahan/McMahon, Hecht, Koch,Breautigam. I put the surnames in order of their importance to me, so if there are too many the first two are the most important. Thank again, jentami
