I have quite a bit of info on the Keck family there were 3 Kecks that came to the USA
Henrich born in Bavaria February 1710 he came to the USA in 1732 his brother came later I believe his name was Johannes. and another Keck came from Germany in 1856 I think I have his name somewhere. he was not related to the other 2. there is a history written by J.A. Keck from Iowa he traveled to Pa in 1905 I believe that is the correct date and stayed with the family of my GG grandfather L. L. Keck and they worked on this info together and talked to other older Keck family members. you can contact me via my email
