Jose Segundo Flores Land Grant
Last Names of Nuevo Leon

Did your ancestor ever receive a Land grant from the Spanish Government or the State of Tamaulipas? If your answer is yes then you will likely find it on the website of the Texas General Land Office.

These records don’t offer much genealogical information but they sure add to your family history. They may also lead to other land records or proofs of heirship that do contain genealogical information.

What the Texas General Land Office has to Offer

The Texas land grant database contains over 4,200 land titles issued by Spain and Mexico from 1720 to 1836 covering 26 million acres. It also offers other collections for a total of 656,129 records.

This is an example of one of the results for one of my wife’s ancestors:

County:  Hidalgo
Abstract Number:  83
Adj County:  Starr
District/Class:  San Patricio 1st
File Number:  000753
Original Grantee:  Flores, Segundo
Patentee:  Flores, Segundo
Title Date: 
Patent Date:  13 Aug 1881
Patent No:  500
Patent Vol:  23
Certificate:  106
Part Section: 
Survey/Blk/Tsp:  27
Acres:  13322.20
Adj Acres:  903

The above entry also contains a link to a 17 page PDF of the records of confirmation by the State of Texas for the land grant.

The image on top of this post comes from that PDF and it represents the “Los Guages” land grant.
