Rancho Las Baulines
Mexican land grant in California
Rancho Las Baulines was a 8,911-acre (36.06 km2) Mexican land grant in present-day Marin County, California, given in 1846 by Governor Pío Pico to Gregorio Briones. The grant extended around Bolinas Lagoon and encompassed present-day Stinson Beach and Bolinas.
History
Gregorio Briones (1797-1863) born in Monterey, was the son of Marcos Briones who accompanied Junípero Serra in 1769. In 1819 Gregorio entered the army and remained in it for eleven years. In 1822 he married Maria Ramona Garcia (1803-), the sister of Rafael Garcia of Rancho Tomales y Baulines. Briones' sister, Juana Briones de Miranda, owned Rancho La Purísima Concepción. Gregorio Briones served as alcalde of San Jose in 1830, Pinole 1832-1837 and San Mateo 1837–1839. In 1837, his son, Jose Pablo Briones (1823-1897), moved with the family's cattle to Rafael Garcia's ranch in the area around Bolinas Lagoon. Garcia moved north up the Olema Valley to his Rancho Tomales y Baulines grant. The rest of the Briones family joined Pablo in 1838 and Gregorio moved there permanently in 1839.

Why this record matters
The subject matters to the general reference register because the source frames it as mexican land grant in California. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q7291048. Authority coordinates are 37.930, -122.680. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1846, 1797, 1863 and 1769.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
