Mary Cromartie

I just received a query regarding Mary Cromartie (daughter of William Cromartie and Ruhamah Doane) and Archibald McNabb. Mary was born in Bladen County, NC on April 7, 1778 and died in Tattnall County, Georgia in March 1860. Archibald McNabb was born in NC about 1770 and died in Tattnall County, Georgia prior to February 27, 1858. They had six children: Daniel McNabb, John McNabb, Hannah McNabb, James Glenn McNabb, Amy McNabb, and Mary McNabb. James Glen McNabb was born in North Carolina on June 17, 1802 and died in Putnam County, Florida on December 5, 1868. I am attaching three documents concerning Mary and Archibald McNabb. First is photo of the Cromartie Family Monument that lists Mary as born in 1778. Second is a page from the William Cromartie Bible which does not list Mary. third is the US Federal Census Mortality Schedules 1850-1885 listing Mary McNabb age 85 at time of her death in March of the year ending in June of 1860 with birth in North Carolina.
