I am engaged in writing a series of essays on the historical experience of Hispanos, i.e., the Spanish-Mexican population of New Mexico, using my family as the handle for exploring various historical moments. Briefly and by example, the first Madrid who enters New Mexico is recorded as being part of a wagon train that arrives there in 1608. His name is Cristóbal, he is 8 years of age, and his oficio is that of chirrionero de carretas. A very high percentage of New Mexicans with that last name are descended from that one person. The principal exceptions are the descendants of genízaros, detribalized Indians who were incorporated into the households of the various Madrid families.
