MARY WALKER born SUGAW CREEK, NORTH CAROLINA - died NORTH CAROLINA

I have found two records for a MARY WALKER that fits our Mary Walker...anyone out there related ....
Mary Walker married to John Black September 1 1790 Mecklenburg, NC...maybe daughter of James and Mary?
Mary Walker and James Rea March 10, 1814 Mecklenburg, NC...maybe a granddaughter of James and Mary ; possibly daughter of Robert Walker?
