This book list an 1812 marriage of a David Nutter to Elizabeth Cox daughter of Henry Cox. I think this is them but I haven't attached this yet until more research. Making a note of it here for reference. Edited to add: there ARE Nutter (surname) in this area. User:cthrnvl
I have found a second transcription that has Nester instead of Nutter. So I am attaching this to this marriage with 95% confidence. But keeping the notes here for reference. Transcription: David Nester Elizabeth Coxes Henry Cocks Nov. 11, 1812 Married by Simeon Harris [1]
