Folsom, Joseph Libbey, 1817-1855.

Joseph Libbey Folsom was born May 19, 1817, in New Hampshire. He was a graduate of West Point and went to California in 1846 as Captain and Assistant Quartermaster of Stevenson's Regiment of New York Volunteers. After the Mexican War, he settled in San Francisco and was the Collector of the Port of San Francisco. He invested in real estate in San Francisco and beyond, notably purchasing rights to William A. Leidesdorff's large estate, the Rancho Rio de los Americanos in Sacramento County. Folsom died in San Jose, California on July 19, 1855, at the age of 38. At the time of his death, he was developing Leidesdorff estate land into town lots, and the resulting town, Folsom, was named in his honor. The executor of his estate was the San Francisco law firm Halleck, Peachy & Billings.
