Rancho San Pablo

A brief history of Rancho San Pablo (Rancho Los Cuchigunes)

NOTE: This excerpt from a 1930s WPA Guide is incorrect. The Alvarado Adobe was built in 1842 by Jesús María Castro (second youngest son of Don Francisco María Castro) for his mother, Dona Gabriéla Berryessa de Castro.

The Partition of Rancho San Pablo

The original grantee of Rancho San Pablo, Francisco María Castro, died in 1831. When he died, one half of Rancho San Pablo went to his wife, María Gabriela Berreyesa de Castro, and the other half went to his eleven children. (Alvino Antonio de Gracia, María Francisca, Pablo Antonio María, Juan José, Vincente, Antonio Gabriel Vincente, Joaquin Ysidro, Albino Antonio Timoteo Pablo, María Gregoria Gertrudis, María Martina, Victor Ramon, María Luisa de Jesús, José María Miguel de Jesús, and Alvino Antonio Mauricio each received a 1/22 share.)

Unfortunately, the heirs each received undivided shares, which meant that no boundaries were drawn to clearly define what each heir owned. Instead, each heir owned either a 1/22nd interest (each the children) or an 11/22nds interest (María Gabriela Berreyesa de Castro) in each square inch of the entire Rancho. Some sold land, some mortgaged land, and in general no one told anyone else what they were doing.

Three of the couple’s children died without heirs, so their interests in Rancho San Pablo reverted back to their mother. When she in died in 1851 she left her interest in the Rancho to her daughter Martina, who was the wife of Governor Juan Bautista Alvarado. This meant that Martina then owned a 15/22nds interest in the Rancho. At one point the other heirs tried to have the will of their mother thrown out. Poorly documented sale and mortgage transactions entered into by the various heirs made the situation almost irresolvable.

The whole mess ended up in the courts in what is said to have been one of the most drawn-out land cases in American history. For a period of about 40 years no one knew what he or she owned. Judge J. C. B. Hebbard released his final decree of partition in March of 1894, thus ending decades of uncertainty about titles to the property in Rancho San Pablo. His decree divided the Rancho among 148 owners.

Gray's Map [Nicholas Gray] 1856.

The property owners of Rancho San Pablo are believed to have commissioned this map to help understand exactly who owned which pieces of land in Rancho San Pablo. Nicholas Gray was a U.S. Deputy Surveyor. A James Forbes was also associated with the project and sometimes this map is referred to as "Forbes's Map." There was also one other person who is listed as having participated in this project but his name is unknown.
