In 1848, a notary public and searcher of records named C.V. Gillespie launched in San Francisco the company that would eventually become Fidelity National Title Insurance. The launch of Gillespie’s business coincided with the discovery of gold in the American River near San Francisco and the resulting surge in demand for land in the area. During the devastating earthquake and fire in 1906, employees and wives of Fidelity National Title Agency’s predecessor company saved the title plant and other important property records. The documents became an invaluable resource when San Francisco’s City Hall and the Hall of Records were destroyed in the disaster. In 1920, Gillespie’s company was founded as the Western Title Insurance Company.
