text: The extensive network of waterways in and around Stockton was fished and navigated by Miwok Indians for centuries. During the California Gold Rush, the San Joaquin River was navigable by ocean-going vessels, making Stockton a natural inland seaport and point of supply and departure for prospective gold-miners. From the mid-19th century onward, Stockton became the region's transportation hub, dealing mainly with agricultural products.

  Carlos Maria Weber was a German émigré in the United States in 1836. He was born as Carl David Weber (February 18, 1814, in Steinwenden – May 4, 1881, in Stockton) and then went by Charles in 1836 in the United States, first spending time in New Orleans and then in Texas. He then came overland from Missouri to California with the Bartleson-Bidwell Party in 1841 and began to go by Carlos, when he began working for John Sutter. In 1842 Weber settled in the Pueblo of San José.
  As an alien, Weber could not secure a land grant directly, so he formed a partnership with Guillermo (William) Gulnac. Born in New York, Gulnac had married a Mexican woman and sworn allegiance to Mexico, which then ruled California. He applied in Weber's place for Rancho Campo de los Franceses, a land grant of 11 square leagues on the east side of the San Joaquin River.
