I have Davis Quaker ancestors from NC, and info on many generations. But I don't see your James or Gabriel. Research William W. Hinshaw's Quaker Encyclopedia Vol. 1-5, it's an index of each of the monthly meetings (MM) in every location. If your family was a Quaker, you'll need to determine their worship location most often named after streams, creeks or rivers, i.e., Cane Creek, Bush River, Elk Creek, etc. You'll find info pertaining to family membership, transfers to/from other MM locations (great for tracking migration), disciplinary notes, births, marriages, deaths, etc. Though Hinshaw's research is considered the authority since he referenced the actual written records, his volumes are a secondary source so ther're may be some mistakes or exlcusions. And there are missing records. Also, there are at least two adendums that I've come accross that were published after the original volumes in early printing, then included in the volumes in later printing.
