It is possible that Jacob and Rebecca are B/S. According to the NJ 1860 census, Rebecca was born in NJ and lived in Salem County with her husband, John Strimple and four daughters. There is a listing in Pilesgrove, NJ of a Jacob Adams b. c1825, chairmaker with Phebe Adams age 46. I have no additional information on Rebecca except for her marriage date. I will look for your Jacob in my research and let you know if I find anything.
