HistoryA character grade: shown, never part of Fallbrook’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Fallbrook’s 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C−. The pre-1940 share (±0.5 points) is firm at this size. Two sources give 1869.

Fallbrook was first inhabited by the Payomkawichum people, later renamed Luiseños by the Spanish missionaries who arrived in the area in the late 18th century. Large village sites and oak groves were established by the Luiseños; one site became the area today known as Live Oak County Park.
The first permanent recorded settlement dates to the Mexican period in 1846, when Ysidro Alvarado received the Rancho Monserate grant from then-governor of Alta California, Pío Pico. The 13,323-acre grant stretched from the San Luis Rey River near Bonsall in the south to Stagecoach Lane and the Palomares house in the north, bounded by Mission Road on the west and Monserate Mountain on the east.
