Mary would have been born on her father's Surry County plantation called "Arnols." Apparently there was little contact with her brothers later in Amelia as no oral tradition or correspondence regarding Mary's family passed to the later generations. She is not mentioned in "Genealogy in part, of the Anderson-Owen-Beall families"; By Grant James Anderson; Richmond Virginia; Whitter & Shepperson printers, 1909.
Dates of birth of her children are from the Albemarle Parish Register. Christening dates are; Amy 11/20/1739, Sarah not given, Anne 01/08/1744, Mary 08/31/1746, James 04/29/1749, Winny 10/20/1751, Susanna 11/25/1753, Elizabeth 08/29/1756, Frances 07/29/1759. There is disagreement in some instance with the work of Eva Turner Clark. Examination of the microfilm of the Albemarle Parish Register at the Library of Virginia will be the only way to resolve any errors.
