Damacio Jimenez, defender of the Alamo, and Tejano headright claim

Tejano defender of the Alamo, heirs attempted to file for war bounty land claim in 1861 [supported by Seguin; petition was denied for non-payment of fees]: Damacio Jimenez.[1]

In its Constitution of 1861, Texas once again opened its court systems for worthy citizens and/or Texas revolutionary war veterans to petition for land, and, as in the Constitution of 1845, a two-year limitations period was imposed.[10]

The 1861 term of court saw such a claim: the descendants of Damacio Jimenez, defender of the Alamo, came forward and petitioned in open court for a headright claim of land as promised by the Constitution of Texas.[11]

Witness in Court: “Sec. 26. All negroes, mulattoes, Indians, and all other persons of mixed blood, descended from negro or Indian ancestors, to the third generation inclusive, though one ancestor of each generation may have been a white person, shall be incapable in law to be witnesses in any case whatsoever, except for and against each other.” [Dec. 22, 1836]

Slave Trade as Piracy: “Sec. 1. … That if any person or persons shall introduce any African negro or negroes, contrary to the true intent and meaning of the ninth section of the general provisions of the constitution, declaring the introduction of African negroes into this republic, to be piracy, except such as are from the United States of America, and had been held as slaves therein, be considered guilty of piracy; and upon conviction thereof, before any court having cognizance of the same, shall suffer death, without the benefit of clergy.

Sec. 2. … That if any person or persons shall introduce into the republic of Texas, any Africans or any slave or slaves, from the United States of America, except such slave or slaves as were previously introduced and held in slavery in that republic, in conformity with the laws of that government, shall be deemed guilty of piracy, and upon conviction therefore, before any court having cognizance of the same, shall suffer death.” [Dec. 21, 1836.]

Militia, Republic of Texas: “every able-bodied male citizen of this republic, resident therein, who is or shall be of the age of seventeen years, and under the age of fifty years, (except as hereinafter excepted,) shall severally and respectively be enrolled in the militia, by the captain or commanding officer of the company, within whose bounds such citizens shall reside….

Possible contemporary sources on genetic diversity, composition of mestizo Mexican population


Analysis of genomic diversity in Mexican Mestizo populations to develop genomic medicine in Mexico


Mexico is developing the basis for genomic medicine to improve healthcare of its population. The extensive study of genetic diversity and linkage disequilibrium structure of different populations has made it possible to develop tagging and imputation strategies to comprehensively analyze common genetic variation in association studies of complex diseases. We assessed the benefit of a Mexican haplotype map to improve identification of genes related to common diseases in the Mexican population. We evaluated genetic diversity, linkage disequilibrium patterns, and extent of haplotype sharing using genomewide data from Mexican Mestizos from regions with different histories of admixture and particular population dynamics. Ancestry was evaluated by including 1 Mexican Amerindian group and data from the HapMap. Our results provide evidence of genetic differences between Mexican subpopulations that should be considered in the design and analysis of association studies of complex diseases. In addition, these results support the notion that a haplotype map of the Mexican Mestizo population can reduce the number of tag SNPs required to characterize common genetic variation in this population. This is one of the first genomewide genotyping efforts of a recently admixed population in Latin America.


Admixture and population structure in Mexican-Mestizos based on paternal lineages

In the nonrecombining region of the Y-chromosome, there are single-nucleotide polymorphisms (Y-SNPs) that establish haplogroups with particular geographical origins (European, African, Native American, etc.). The complex process of admixture that gave rise to the majority of the current Mexican population (~93%), known as Mestizos, can be examined with Y-SNPs to establish their paternal ancestry and population structure. We analyzed 18 Y-SNPs in 659 individuals from 10 Mexican-Mestizo populations from different regions of the country. In the total population sample, paternal ancestry was predominately European (64.9%), followed by Native American (30.8%) and African (4.2%). However, the European ancestry was prevalent in the north and west (66.7–95%) and, conversely, Native American ancestry increased in the center and southeast (37–50%), whereas the African ancestry was low and relatively homogeneous (0–8.8%). Although this paternal landscape concurs with previous studies based on genome-wide SNPs and autosomal short tandem repeats (STRs), this pattern contrasts with the maternal ancestry, mainly of Native American origin, based on maternal lineages haplogroups. In agreement with historical records, these results confirm a strong gender-biased admixture history between European males and Native American females that gave rise to Mexican-Mestizos. Finally, pairwise comparisons and analysis of molecular variance tests demonstrated significant population structure (FST=4.68%; P<0.00005), delimiting clusters that were geographically defined as the following: north–west, center–south and southeast.
