The ancestors of the Aragons go back quite far. however at present time our Aragons from Anton Chico run into a dead end sometime around the early 1700s. I will pull up what I have tommorrow and show you what I have.My Aragons also are from Anton Chico, and were once the holders of the San Miquel Del Vado grant. Later La Liendre. My great grandmother was Vidalia Montano Aragon, and she was the daughter of Jose Longino Aragon and Maria Teodora Isadora Romero.
There are other families that they connected to such as the Baca, Gallegos, Sandovals, Rael, Ortiz, and others. The earliest direct Aragon ancestor that is proven is Nicolas Aragon born 1701 in New Mexico, and died 1751 he was married to Margarita Gallegos born 1706 in New Mexico. My Montano ancestry connects with the early settler Ignacio Aragon, who is thought to be the first New Mexico Aragon. I think that someday it will probably be proven that the Anton Chico Aragons are descended from Ignacio, but as yet, it is not proven.
However, the family tree of the Anton Chico Aragons goes back a long way and if you are a descendant of Jose Longino Aragon who was born in 1824, and died on 9 March 1891 in La Liendre, you will have ancestors that go back to some of the earliest conquistadors.
This much I can truly say. The land grant families did tend to marry their children off to the children of other land grant families, and so the Aragons have ancestors from most of the first families of New Mexico, and many of those did come to New Mexico with Don Juan De Onate in the 1590s.
