First let me tell you that my husband is related to the John Parks that married Nancy Cooksey.
I know Zilpha/Zelpha Rayburn had a son Cader Price and other Parks children
Do you know about theBurrell/Burwell Rayborn/Raburn? Burrell had a sister Tabitha Rayburn who married Aaron Parker.Aaron and Tabitha had at least one daughter Sintha Parker born 1804 in TN.She married in Dec 1820 to Alexander Graham born 1801NC.
This is the Alexander Graham who in Newton county, MS in 1840.
I have hopes of located the Rayburn family to help locate the Parker family.
