Anna Aller (1809-1890), NJ

One of my gggrandmothers was Anna Aller (3/13/1809 - 9/4/890). Her parents were Henry Aller (3/6/1783 - 5/13/1868) and Eleanor "Ella" Best (2/3/1789 - 1/13/1877). Henry and Eleanor farmed in Sidney, Franklin Township, Hunterdon County and are both buried at the Bethlehem Presbyterian Church at Grandin, not far from present day Clinton, New Jersey. However, I have been unable to identify the parents of eithe Henry or Eleanor with any certainty. Does anyone reading this thread have any information that could throw light on the Henry's parentage?
