Previous Jurisdictions and Record Repositories
Locating records of your ancestors


 * Find where your ancestor lived
 * Identify when your ancestor live there
 * Locate the jurisdiction covering the land where your ancestor lived
 * Determine the record repositories for that jurisdiction

For example, suppose you believe your ancestor lived in Tucson, Arizona in 1861.


 * In the present day, Tucson is indeed located in the State of Arizona.
 * But Arizona didn't exist in 1856. Arizona Territory wasn't created until 1863.
 * Before that, the land belonged to New Mexico Territory, which was created in 1850. So your ancestor lived in New Mexico Territory. This jurisdiction still exists today as the State of New Mexico.
 * In 1853, the US bought the Gadsden Purchase from Mexico, which contained land south of the Gila River. This is the land where Tucson is located. In 1854, this land was given to New Mexico Territory and in 1855 this land was added to Dona Ana county.
 * Then in 1860, New Mexico created Arizona county from the land in Dona Ana county. Arizona County existed totally within the present day State of Arizona. So your ancestor lived in Arizona County in the New Mexico Territory. But Arizona county was discontinued in 1862, then recreated in 1863 and finally discontinued again when Arizona Territory was created in 1863. The records from this extinct county are found in the present day in Dona Ana County in the State of New Mexico.

Putting this altogether, your ancestor actually lived in Tucson, Arizona County, New Mexico Territory in 1861. Therefore look for records in Tucson, Dona Ana County, and the State of New Mexico archives.

Sometimes, records were recorded in a county where your ancestor did not live. Maybe there was confusion as to where the borders lay. Or maybe it was a shorter distance to the neighboring county seat. There could be several reasons, so don't overlook records in nearby counties. But treat this as the exception to the rule and check the most obvious county first.

Spanish and Mexican land (from 1820 to 1846) that would later become Arizona
Spain laid claim to much of the land in the present day southwestern US. Because of the great distances and the hostilities of the Indian tribes, Spanish rule was only extended to the southern portion of present day Arizona, and at times not even that much. Tucson was the only permanent town established.

Spain establish the practice of giving land grants to encourage settlement on the fringes of their rule. Mexico continued this practice. All Spanish and Mexican land grants were located in the Gadsden Purchase. If you stand in downtown Tucson and and look to the southeast corner of present day Arizona, then turn 90 degrees to your right along the border. All of these Spanish and Mexican Land Grants are located in that triangle.

1820 - The San Ignacio de la Canoa Grant. Two brothers petitioned the governor of Sonora/Sinaloa for four leagues (sitios) to raise cattle and horses. Title was issued by Mexico in 1849 and Court of Private Land Claims confirmed the grant in 1899. This land grand was located on both sides of Interstate 19 south of Green Valley (that town is in the northwest corner of the grant).

1820 - The San Bernardino Grant south of Bisbee was also applied for by Ignacio de Perez, a Spanish lieutenant, who paid $90 for four leagues. The grant was surveyed in 1821 and recorded in Arizpe, Sonora but no title was ever issued. Most of the grant is located south of the border. The Court of Private Land Claims confirmed only the 2,383 acres that are on the American side.

1821 - Southwest of Patagonia is the San José de Sonoita Grant, the smallest grant made in Arizona. It was applied for in 1821 by Leon Herreras, a resident of Tubac, who had it surveyed and who received a Mexican title in 1825 for 7,598 acres. Court of Private Land Claims rejected that title on the grounds that the treasurer of Sonora had no authority to sell land in that area, but U. S. Supreme Court overturned the rejection. However it only confirmed 5,123 acres.

1821 - The San Rafael de la Zanja Grant, just to the north of the Mexican border, east of the Patagonia Mountains. The four-league grant was sold at public auction for $1,297 and title was issued by Mexico in 1825. Court of Private Land Claims confirmed the grant in 1902.

24 Aug 1821 - The Treaty of Cordoba was signed by Spain, which recognized Mexico's independence. Land in present day Arizona became part of the Republic of Mexico. But effectively Mexico only controlled the southern part, which was placed in the State of Vieja California. Look for records in the Spain and Mexico Archives.

1827 - The Buena Vista Grant straddles the international boundary just east of Nogales and two thirds of it is in Mexico.

1827 - The San Ignacio del Babocomari Grant looks on a map like a twenty miles long boomerang north and west of Fort Huachuca. The petitioners paid in 1827 all of $380 for the nearly fifty-three square miles of the grant.

1827 - The San Juan de las Boquillas y Nogales Grant is located along the San Pedro River west of Tombstone. Title was issued in 1833
