Pima County, Arizona Genealogy

Pima County, named for the Pima Indians, is in southeastern Arizona. Today it is home to Arizona's second largest metropolitan area, which includes Tucson, which is also its county seat, and the location of many records of value to researchers of this area.

It is part of the 'Gadsden Purchase', the last area in the lower 48 United States to be ceded to the United States by Mexico. Tucson itself had been a community for many years and in 1847 the United States flag was first raised over Tucson by the United States Mormon Battalion, the party that blazed the southern route across to San Diego.
