The border between Rancho Los Guilicos and Rancho Agua Caliente seemed to be defined by Calabezas Creek in the May, 1859 survey. It should be noted that the size of the rancho increased to 42,800.00 acres from 18,833.86 between the surveys of 1859 and 1865.

The Guillicos valley is in fact the upper part of Sonoma valley proper. It is one of the most beautiful places in California. It was originally granted to the wife of Don Juan Wilson, a famous sea-captain on this coast under the Mexican regime. He married into one of the native California families, and though an Englishman by birth, he became a Mexican citizen, and was granted the Guillicos valley. In 1850 it was purchased by William Hood, who subdivided and sold the greater part about ten years ago. He, however, retains his beautiful homestead at the foot of the Guillicos mountain, one of the most picturesque as well as one of the most valuable farms in California.
