Dear Mr. Tellez,
Thank you for posting your request on History Hub!
As birth records often contain parental names, we suggest that you search for a record of Wenceslao Beltran’s birth in the FamilySearch Texas Births and Christenings, 1840-1981 index, request a birth record search from the Starr County Clerk, and review the FamilySearch Research wiki for Starr County, Texas Genealogy.
We hope this is helpful. Best of luck with your research!
