Kathy,
I am the son of a Klingensmith daughter. There is a Doctor at the University of Pittsburgh that has done a complete history of the Klingensmith's all the way back to the 13th century. I do not recall his name at this point and time but he was given a lot of money from the government to research a rare cancer that the male Klingensmith's are very susceptible too. I will get you his name and number as soon as I can. I do not know if he ever compiled and published his findings but he did dig up an awful lot of interesting info. For instance, The Klingensmith family helped Martin Luther with the reformation of the Catholic church and helped start the Lutheran church. The pope actually had a contract out for the heads of the Klingensmith's back then.
Goodbye for now. If you send me your e-mail address I will send any info I get on. Oh someone has published a family history book my aunt has one. Steve
