This is the only information I found listed: The 1774 rateable of Northampton Twp name but one Fenimore, Richard and Sarah's son, William. Perhaps both parents were deceased by that date. There is the possibility, however, that Richard and Sarah moved to Pennsylvania. Richard's cousin Samuel was living in Philadelphia Co., Pa by 1756. Many Burlington Co. families moved via Pensylvania into the Shenandoah Valley around 1750, others located in the upper Susquehanna River valley around 1765, fiving rise to the Pennamite Wars.
