Soza family papers

The Soza family was founded in 1746 by Jose Maria Soza I, a cavalryman in the Royal Spanish Army who was stationed at Presidio San Ignacio de Tubac in 1774 and was later transferred to the Presidio San Agustin del Tucson, with his wife, Rita Espinosa, with whom he fathered one son and three daughters.

Jose Maria So Soza II was the Civil Administrator of the Tumacacori Mission during the 1830’s and was married to Dona Gregoria Nunes. They had eight children.

Jose Maria Soza III married Solana Mendoza in the early 1850’s. Their daughter, Manuela Mendoza Sosa married Michael McKenna, a Civil War veteran, and they created the McKenna branch of the family.

The descendants of the Manuel and Calistro Sosa branch included the families of Antonio Campa Soza, Placido Campa Soza, Nicolas Campa Soza and Juan Soza. The Juan Soza branch became early settlers of Tempe, Arizona and have roots with the Hayden family. They were later joined by the Placido Sosa branch.

The Antonio Soza branch of the family has long been associated with Tucson and the San Pedro River Valley, where Antonio homesteaded and was engaged in farming and ranching.
