It is the family of Jonathan F Davis (1829 - 1900) and wife Cornelia Dillard, of Granville County, NC.
I believe Jonathan descends from Richard Davis (b: Abt. 1700 in Wales d: 1761 in Granville Co. North Carolina) and his wife Elizabeth, though I have no source documentation of the family linage past Jonathan. Only speculation.
Sorry, I should have included this information in my original post!
