Jose Miguel born 1790, Higinio born 1819-20, Benito Salinas born 1861 information from cameron co., tx-my ancestors

I been searching and have some information on Jose M Salinas, Higinio,--burial sites and for
Benito (who married my ggrandmother (Josefa Cantu). I wonder where Benitio Salinas or she was buried. Did he live in Dilley, Tx with Nazaria (my grandmother) or her sister Enriquetta Salinas Perez. No info on his gravesite. I would appreciate any more infomation. Thank you.
I found Enriquetta's info and Nazaria's but not Benito or Josefa's burial site in Tx.
