Many people came to California by ship, either around the horn or via Panama (yes, I know the canal wasn't there then--they took two ships, one on either side). There are a good many records of those folks. But many also went back home by ship, having made thir fortune or given up, or for other reasons. I know some who did and wonder about others. Are there records of passengers leaving San Francisco, particularly from 1855 to 1860? Thanks, Jim
