History

The town of Angwin is named for Edwin Angwin (1841–1919), a native of St. Agnes, Cornwall, who in 1875 purchased a 200-acre (0.8 km) parcel within the Rancho La Jota on Howell Mountain and established the Angwin Resort. By the 1900s, Mr. Angwin owned almost 1,600 acres (6.5 km) of land in the area.

Prior to 1875, Rancho La Jota was held in its entirety by William Campbell Watson, husband of Elizabeth Anne Davis, the granddaughter of George C. Yount. Mr. Watson began to sell off portions of the Rancho in 1875, Mr. Angwin’s being among the first parcels. Soon after a community began to emerge with the success of, and in support of, the Angwin Resort.

In 1909, Healdsburg College (formerly Healdsburg Academy), a Seventh-day Adventist college, moved from its location in Healdsburg when it purchased the Angwin Resort for $60,000 to open Pacific Union College. According to a 1985 KRON-TV news report, more than 80 percent of the population of Angwin belonged to the Seventh-day Adventist Church.

In August 2020, Angwin was evacuated due to the Hennessey Fire.
