I am a descendant of the Robert Adams of Searcy County AR that you list as a son Matthew and Esther.
I would love to believe that are the same person but so far no one has been able to tie them together by anything other than they have the same name and both married a Cynthia. Do you have proof, such as Bible records this is the same man.
Just in case you don't have it Agnes Wilson is the daughter of Matthew and Catherine Hubbard Wilson. If you E-Mail me privately I can provide the address of someone who has done research on Matthew and Esther.
