I, too, am descended from John Ince of Ireland and his seond wife, Elizabeth "Betsy" Clark. They married in NC in 1812. Their daughter, Agnes Campbell Ince, married Elias B. Nance and had my great-grandmother, Sarah Jane Nance, who married Joseph C. Conner in Hill County, TX in 1867.
Now if we could just find where John Ince lived in Ireland and who his parents and siblings were. Maybe one of our new subscribers will be able to provide some clues.
