Just go ahead and start your family tree! That'll serve as an outline and you will not be overwhelmed with names/dates. I'm not related but am volunteering to assist your search. I also hope plan to help you develop research skills to gain independence? First, logon https://familysearch.org/
and setup a "free" user account. You'll need that to access Texas Death Certificates and marriage data (when available). Next, save findagrave.com as an icon. You'll make good use of that site. From findagrave, lookup R. Burleson in Jefferson County, OK. He was Raymond P. Burleson born 30 Dec 1924 in Young County, TX. His father was Wiley G. Burleson (30 Aug 1881 - 16 Dec 1926). Lookup W G Burleson death 1926 in Texas on familysearch website. R. P.'s mom was Senith H. (Gradner) Burleson (26 Aug 1895 - 28 Jan 1971). Delbert was the informant on her certificate and that's proof we have the "right" family. Work with that while I try to locate Senith prior to marriage. Suspect her maiden name was Gardner vs Gradner?
