After researching a bit more it appears the Antonio Acosta and uncle Beto are not the ones you are looking for . The Antonio I have was born in 1859 about the same as the one you are looking for and they both had uncles Beto or Veto, but the rest does not match. I aplogize for sending inaccurate data.
If your Antonio Acosta was born in Nacogdoches, I believe the two are related but how I cannot tell as of now. I did find your Antonio Acosta marred to Emma MCCracken and living in Travis county, maybe Austin, as early as 1920 and also in 1930. The uncle Veto listed was born about 1845 which would not have been my uncle Beto who was born in Nacagdoches in 1864 and moved to Wilson County around 1865 or so.
There was an Emma MCCracken age 5 in the 1880 census, daughter of J.M McCraken and wife Mary living with 4 siblings in Parker County.
Also I saw you Antonio Acosta had a son Hugh (wife Benita) and daughter Lillie.
I believe there are some common connections. The Acostas in Nacogdoches were most all related. Some of the Herreras from Nacogdoches, related to my famly also moved to Wilson county and lived in the Area where the Acostas had their farm. Jose Maria Acosta's father Juan Isidro Acosta was my own Greatgreatgrandfather Luis Ramon Acosta's uncle, all in Nacogdoches.
Good luck with your search and again I apologize for misinforming you.
