The first message was written in such a hurry I didn't have a chance to edit, nor did I provide pertinant information I have available.
The Texas General Land Office (TGLO) does not have information as to how the land was divided, on Juan Narciso Cavazos heirs, nor any genealogical information. I do not yet have a copy of the sketch that describes the San Juan de Carricitos land grant;I just recently obtained the information. One must reference the file number of San Patricio 1-764 when ordering.

("The Handbook of Texas Online"). This site has a tremendous amount of historical information that may be of help.
This is not on the web site. In the late 1800's and early 1900's, Presbyterian missionaries visited south Texas and converted half of the Cavazos family and other Spanish families from Roman Catholic to Presbyterian. The missionaries visited two ranches. One was called "El Rancho Alazan" (Cavazos and Garcia) and the other was either the "Rancho Arroyo Colorado" or the "Rancho Espirito Santo" (Lopez, Saldana, and de la Garza). My grandfather lived on Cavazos/Garcia ranch and grandmother on the other ranch. One ranch was in Willacy County and the other in Cameron county. The county line ran between the ranches. Two of my granfather's brothers became Prebyterian ministers (Juan Cavazos of Edinburg, Texas and Desiderio Cavazos of San Benito, Texas.
My grandfather's name was Rogerio Garcia Cavazos and my great grandfather was named Juan Napumocemo Garcia Cavazos.
This Cavazos or Cabazos family came from Spain as far as I know. The family name is found spelled both ways, describing the same person, (e.g., Juan Narciso Cavazos and Juan Narciso Cabazos who was granted 601,657 acres in South Texas (Mexico) as the "El Agostadero de San Juan Carritias" or "San Juan de Carricitos" land grant in 1792. This was the largest land grant in South Texas.
However, in 1963, in the court house in Brownsville, TX, I read where there were two brothers, one of which was named Juan Cavazos, had been given the "San Juan de Carricitos" land grant by the King of Spain in 1709. I also saw a map showing the boundries and the homesteads. Shame on me for not making copies.
Hope this informatin helps.
