I have yet to establish my connection to this line. My ancestor was a Jacob Feller, found in Greene County, TN. which borders Washington County. in 1798, but he is not the Jacob G. Fellers, son of Adam. I believe he is related farther back, but I can't find the parents names of my Jacob, who was listed as born in Pennsylvania, in the TN. Vital Statistics Record, at his death in 1860. By looking at the maps, my ancestor and yours only lived a few miles apart, so I am leaning to "kinship" at this time. It could be a coincidence, but I'm not convinced of it yet.
