 Using the terms set by Figueroa, the first land grant issued in that area was approved by Estudillo himself, as "alcalde" on June 2, 1836.The recipient of that land grant was William A. Richardson, who had just become Estudillo's brother-in-law.After his one-year term, Estudillo, his wife, and ten children moved across San Francisco Bay, settling just outside the Peraltas' Rancho San Antonio on San Leandro Creek, the first settlers in what would later be known as Eden township.
