The vibrant East Bay city of Hayward was named for William Hayward, a '49er and American squatter who endeared himself to Mexican landowner Guillermo Castro by making him a good pair of boots. With Castro's permission, William stayed to open Hayward's Hotel on what is now Main and A Streets. That fortuitous location, near the convergence of the eight tributaries forming San Lorenzo Creek, made the region a natural transportation hub between the bay and the fertile Livermore Valley. Stagecoach lines, a narrow-gauge railroad, and later modern transportation links encouraged more immigrants to settle. Today Hayward is a diverse city of almost 150,000 people, and home to a campus of the California State University.
