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 km2) parcel within the Rancho La Jota on Howell Mountain and established the Angwin Resort.[5] By the 1900s Mr. Angwin owned almost 1,600 acres (6.7 km2) of land in the area.[6]

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 being amongst the first parcels. Soon after a community began to emerge with the success of, and to provide support to, the Angwin Resort.

In 1909, Healdsburg College (formerly Healdsburg Academy), a Seventh-day Adventist college, moved from its location in Healdsburg, California when it purchased the Angwin Resort for $60,000 to open Pacific Union College.[7]
