In early July of 1845, Felipe Sena, on behalf of the Departmental Assembly of New Mexico, complained about the granting of land in Doña Ana. He argued that Doña Ana was in New Mexico (not Chihuahua), and proposed that the titles to land in Doña Ana be suspended pending re-granting of the lands by New Mexican authorities. (The Spanish Archives of New Mexico Vol. I, No. 257.)
In 1839, Jose Maria Costales of Chamisal submitted a petition to the local Prefecture of Paso del Norte, asking that over a hundred families of El Paso be allowed to settle “el punto de Doña Ana.” The Prefecture then forwarded the petition to state officials of Chihuahua.
Why was the petition to settle Doña Ana sent to authorities in Chihuahua, instead of New Mexico? The answer: at the time, Paso del Norte and Doña Ana were in the jurisdiction of the State of Chihuahua. After the Mexican Independence, the State of Chihuahua’s northern border extended north of Paso del Norte (and north of Doña Ana) to the paraje de San Diego.
