    Biographical / Historical

    The Porter legacy in California stretches back to the Gold Rush Era, when a trio of Porter cousins, George K., John T., and Edward F. "Ned" Porter, made their way from New England to Santa Cruz County and engaged in a wide array of entrepreneurial activities.
    In 1854, another cousin, Benjamin Franklin Porter made his way to California by crossing the Isthmus of Panama on foot, before joining his family members in Soquel. He became active in the local economy and, in the mid­ 1850s purchased the Soquel Tannery along with his cousin George and C.W. Moore.
    In the autumn of 1867, Benjamin returned to New England, where he married his childhood family friend, Kate Hubbard. The couple returned to California, where they started a family. Mary Sophia "May" Porter was born in Soquel on October 9, 1868. Mary's sister Sadie died of typhoid fever at the age of 24. Mary was the lone descendant and heir of her father and mother's vast estate, and of her Uncle Ned's, who also had extensive residential and commercial holdings in the Soquel township.
    In 1896, Mary married William T. Sesnon, of Alameda, a businessman and civic leader who served as clerk of San Francisco County. William expanded the Porter family business and real estate holdings into successful oil ventures, manufacturing sites, and land development. The couple had four children - Porter, Katherine, Barbara and William Jr., who were raised spending their summers at the Pino Alto estate in Soquel.
    When William Sr.'s health deteriorated in the late 1920s, the once thriving salons at Pino Alto came to an end. William died in 1929, and Mary passed away the following year. The property was eventually sold off, first to the Salesian order, before it was finally purchased by Cabrillo College in 1978, where it became known as the Sesnon House.
    Descendants of the Porter-Sesnon clan have always been active and generous in the community. Porter College at the University of California Santa Cruz is named after Benjamin Franklin Porter, while his daughter's love of art is memorialized at the Mary Porter Sesnon Gallery.
