Hi Jill, Do you know who the Mary Abernathy was who married a William Cobb in Lincoln County, NC on 7 Aug 1787? They had a daughter Dicey? who married the Rev. William Richards and went to Missouri apparently with the George Bollinger group about 1800. George Bollinger had a Spanish land grant at Cape Girardeau, MO in 1797. I couldn't find parents for Mary.
I accidentally found this looking for something else and remembered that you had the Cobbs. There are two web sites below about the family.
