[1] During this mandate, Músquiz defended the American interests of Texas and tried to get their petitions approved, mainly slave ownership, the practice of smuggling, and defence against the Amerindians who frequently attacked their communities.
He also tried to resolve disagreements between the Americans and the territory's Mexican authorities, although he rejected the convention that took place in San Felipe in October 1832 as illegal and opposed the Anglo-American troops.
[2] During the years of his mandate, in several of his letters to the viceroy of New Spain, he complained about the establishment of a foreign colony in Austin, because its inhabitants were speaking English, not Spanish, the official language of Texas.

Following this, in 1857, Father José María Villarreal Montemayor, claimed the water from the Confraternity of the Immaculate, property of the inhabitants of the village of San Francisco in Tlaxcala and, although they gave a large sum of money, he get the title of ownership.
He refused to deliver the flow of the confraternity of the Virgin of Zapopan, that he previously divided among his family, so Múzquiz was forced to banish him, sending him into exile (he returned years later).
[3] Don Ramon Músquiz married with Tejano[3] Francisca Castañeda[3][2] in San Antonio on December 16, 1823, and had eight children in a period of more than ten years from 1825 to 1847.
