In 1858, he sold it to Benjamin Davis Wilson, of early Pasadena development, the second Mayor of Los Angeles, and namesake for Mount Wilson in the San Gabriel Mountains. In 1884, Wilson sold Rancho San Jose de Buenos Ayres, at 2,000 acres (8 km²), to the nephew of leading pioneer William Wolfskill, businessman John W. Wolfskill, son of Mathus (Mathius) Wolfskill, William's younger brother. He paid $10 an acre and built a ranch house, near the present-day Mormon Los Angeles Temple.
