hi Doris thanks for e-mailing me and the tip. you say yourJacob Zimmerman was in Mohawk Valley in 1712 and he had several sons. you asked for dates. Walton was born 1926. his dad was born approximately 1898. my granddad Asper's nephew Roy Zimmerman was born 1889. i have no other names or dates. i know this is not much to go on. i'd appreciate any suggestions you have. do you know are Rumbergers Jewish?
