An excerpt from the article 18 facts about John Sutter
His son, John Augustus Sutter Jr., proposed the name Sacramento, derived from the Sacramento River. Construction began in December 1848, 2 miles south of Sutter's Fort. His father was not confident nor content of the city foundation as his fortune was ruined, and he didn't want to risk again.
