Rancho Petaluma
Rancho Petaluma was a 66,622-acre (269.61 km2) Mexican land grant in present-day Sonoma County, California given in 1834 by Governor José Figueroa to Mariano Guadalupe Vallejo. Rancho Petaluma stretched from Petaluma River on the west over the hills and down to Sonoma Creek on the east, including all land that lay between these two waterways from the edge of San Francisco Bay to approximately the present site of Glen Ellen. The rancho included present-day Petaluma and Lakeville.
In 1833, Lieutenant Vallejo was ordered by Governor Figueroa to examine the country north of Mission San Rafael, and to visit Fort Ross and Bodega Bay. On his way to Fort Ross, Vallejo crossed the fertile valley of Petaluma. Later, he built a small house and a corral, and in the spring he was ready to petition for a grant of land where he could place his livestock. The land grant was approved by Governor Figueroa in June 1834. Governor Figueroa gave Vallejo vastly increased powers; his title was Military Commander and Director of Colonization of the Northern Frontier, and he was specifically requested to take charge of the mission at Sonoma, reduce it to the status of a parish church, free the Indian workers, and distribute the mission lands and other assets among the population at large. The ten square league (approximately 44,000 acres (178 km2)) grant was confirmed by Governor Manuel Micheltorena and increased by five square leagues (approximately 22,000 acres (89 km2)) in 1843. Although Vallejo's rancho was centered on Petaluma, he made his home in Sonoma.
