Hi Jim, Yes, I have a couple sources about the Abercrombie family moving to North Carolina. 1. I have a monograph written by Eva P. Cooper (great granddaughter of Mary Abercrombie Cooper) dated Aug. 4, 1940 and titled "Traditions of the Cooper Family." 2. Duckett Cooper Morgan, granddaughter of Mary Abercrombie Cooper (married names of Coulson and Williams) wrote out (or dictated) her family's history in 1878 when she was elderly. She also stated that the family moved to North Carolina.
It remains a mystery as to why the Abercrombies moved to NC. Perhaps other relatives in the area? We may never know! Happy researching, Ruby
