I have only this much information on Ann Pullam which I obtained from the "three Sisters" Charles Powell's decendants.
My line is from Ann & William's daughter Sarah Sandridge m Anthony Gholson.
"William Sandridge (Sandidge) was baptized in New Kent County, VA July 1 0, 1698. He married Ann Pulliam. William Sandridge's will , march 10, 1746, is recorded in Spotsylvania County, VA. He wills 100 acres to his grandaughter Sarah Gholson and mentions his son-in-law Anthony Gholson. Ann Sandridge, his widow, married Joseph Martin in 1754. The know children of William & Ann are as follows.
Mary mar. Anthony Gholson, Jr. before 1743 * to Halifax Co. VA (Mary Gholson married John Brown Aug. 8, 1788, Halifax Co. VA and died after 1798.) William mar. Elizabeth Graves James mar. Jane Shelton David mar. Ann Pulliam John mar. Susan Languire and/or Keziah Gatewood."
