This looks to me like a pretty solid match, at least through Paddy (married to Nancy Jean Roberts). Exciting to see this kind of correspondence! Before Paddy, our data has similarities (many of the names), but doesn't match exactly. I'll pass your data to my cousin (I had called her an Aunt before; she's actually my father's double first cousin, so I have no idea what that makes her to me). She's hoping to get on the Web soon, so perhaps she can engage us directly with her latest research.
Back to the data before Paddy: My cousin's information shows Paddy's father as Henry (b. 1802, Rutherford Co, NC), married to Mira Pull in 1824 (same location). Henry was the son of James & Katy (Stringfield), married 1799, NC. This James was the son of James & Lucy. So our data diverges at Paddy's father & grandfather, but re-unites at Paddy's great-grandfather as James & Lucy.
In summary, your data has Paddy descending from John, son of James & Lucy, whereas mine has Paddy descending from James, son of James & Lucy. Unless James & Lucy had two great-grandsons nicknamed Paddy who each married a Nancy Roberts, I'd say that the mismatch noted above could be rectified, & that we share a great-great-grandfather: Paddy Keeter.
As to the family reunion: our branch of the tree has reunions every three years or so, usually in Marion Co & Baxter Co, AR (Yellville & Mountain Home are the county seats). I've never made it to one, but I'll keep trying. Hope yours goes well.
