History

Karl David Weber (1814-1881), born in Steinwenden Germany, immigrated to America in 1836, and after spending time in Texas, came overland from Missouri to California with the Bartleson-Bidwell Party in 1841. Shortly after his arrival, Karl called himself Charles. Weber went to work for John Sutter who vouched for "Carlos Maria Weber" to the Mexican authorities. In 1842, Weber settled in the Pueblo of San José and became a business partner of Guillermo (William) Gulnac. William Gulnac (1801-1851), born in Hudson, New York, was a blacksmith and fur trapper who came to the Pueblo of San José in 1833. William Gulnac married Maria Ceseña, sister of Liberata Ceseña patentee of Rancho Laguna Seca, and became a naturalized Mexican citizen. He was elected as regidor in 1839. Weber and Gulnac operated several businesses. They set up a corn-mill, ran a bakery and a smithy, mined for salt, made shoes and soap, and kept cattle and horses.
