Several other Ancestry.com online trees list the family as having a son named Rayford Parker b. 20 Mar 1872 in Pike, Ark .. d. 18 Jul 1910 in Salem, Pike, Ark. Other trees list a Thomas Parker with the exact same b. & d. data. Unfortunately none of these trees offer any proof or valid sources about Rayford or Thomas Parker. Those which do list sources only cite other (unsourced) family trees or The One World Tree which is, by no means, a factual source.
If anyone has valid information about the other two children of Samuel & Margaret Parker, I’d very much like to hear from you….
