Mother: Sarah Reeves
Birth: 1750-1760 Granville County, North Carolina
An inventory of the Valentine Tudor Farm Cemetery in Madison County, Kentucky where Valentine and his wife are buried lists the grave of a Caroline Hicks (sister-in-law to Valentine). This is an indication that the Betsy Hicks Valentine married did not belong to the family of Robert Hicks and Sarah Reeves. See inventory of this cemetery at https://www.wikitree.com/wiki/Tudor-124.
Much research is needed on this family.
