I am Gary Bruce Preston, a direct descendant of James W. Preston, I have been able to determine the link as far back as James and am stuck. I do not believe that James' father is Moses Preston as some may believe because of the locations they both lived at when they appear in the censuses. Also, James married Hannah Mooberry in 1842. I believe there is a link back to Richard of Calvert County/Calvert Cliffs but can't connect from James back into the 1700's. I'd appreciate any help. Thanks.
