Captain Cristobal Baca and Don Pedro Gomez Duran y Chavez arrived in the San Gabriel colony from Mexico City, and Josefa Baca began assembling the 40-square-mile tract that became known as El Sitio de San Isidro de Pajarito Land Grant. Her granddaughter, Josefa Apolonia Baca, married Clemente Guiterrez, a wealthy traveler from Aragon, Spain, by way of Mexico City, and together they expanded the family’s landholdings, built acequias, developed farmlands, and became prosperous traders who dominated the sheep trade along the Camino Real to Mexico. The Gutierrez family managed the business interests of the Catholic Church, served as military and political leaders, employed many villagers, and held peons and slaves. Later, Julianita Guiterrez, Apolonia’s great-granddaughter, married James Lawrence Hubbell, a soldier in Kearny’s Army of the West, who became known as Santiago. Together they built a grand estate and established a multicultural homestead that extended the family’s economic, social, and political influence into the 20th century. Captain Hubbell led a local company of New Mexican Mounted Volunteers in the Union Army and later served with Kit Carson in campaigns against the Mescalero, while their son J.L. Hubbell built his first trading post on the Navajo Reservation. The history of these families reflects larger struggles and developments in New Mexico and the Southwest, including survival, rivalry among powerful families, peons and slaves, Civil War battles, Indian traders, and early farming and ranching.
