If you are interested in the Aragon and Montano lineage, it is very extensive. To begin with you need to buy a copy of "Origins of New Mexico Families", by Fray Angelico Chavez. The ancestry of these two families is very ancient. There are a number of documents on Jose Montano and wife Vidalia. the 1852 date for the birth of Jose Montano is from his obituary, and was from the memory of his surviving family. The 1850 Census, and several other documents show that he was actually born in 1848. The first Montano we have record of is Juan (pardon me, I am saying this from memory, I will get my notes out later) Montano de Sotomayor. If I remember correctly, he came with the expediton of Don Juan de Onate in 1598. The first recorded Aragon was Ignacio de Aragon. You will find your ancestors are connected to many historical events, and will also find that they connect with many of New Mexico's first families such as the Baca, Romero, Robledo, Ortiz, etc.
I have a copy of Jose Montano's photograph if you are interested, also a bit of his service record when he served with Kit Carson and the 1st New Mexico Volunteers. Much more. Lot's of history in your ancestry.
