Rancho Los Putos also called Rancho Lihuaytos was a 44,384-acre (179.62 km2) Mexican land grant in present-day Solano County, California given in 1843 by Governor Manuel Micheltorena to Juan Felipe Peña and Juan Manuel Vaca.
The grant encompassed present day Vacaville, all of Lagoon Valley and stretched into what is now, Yolo County almost to Davis.
General Vallejo is credited with recommending the Lagoon Valley area to Vaca and Peña.
[2] With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
In exchange for laying out the town and tending to the legal paperwork, Mizner received half of the land in the deal with Vaca.
The jury found Vaca guilty of libel, but the California Supreme Court overturned the decision, ruling that Vaca's newspaper warning was something that “every freeman and freeholder would be justified in making if the circumstances raised a strong presumption that the fraud had been attempted upon him to get possession of his estate”.
A survey correcting the boundaries of the William Wolfskill Rio de los Putos grant and the Vaca-Peña Rancho was made in 1858.
[8] The legal fees for the years 1853 through to the official United States patent in 1858, were paid in land.
