Try the LDS family search for Christian Schluep born Feb.5, 1792.I think the family lists your John and Magdelena. these families somehow are related to mine as they came from Nennigkofen and Luesslingen (in Solothurn).There were so many in Ohio. And a lot from Nennigkofen where I know mine were from. Use the spelling Schluep. I just can't put the entire family together in this country! I will persist.
