Rocklin is located just North of Sacremento.  Many Chinese came over in the Gold Rush and to help build the railroads, but there were expulsions when the economy went south in the 1870's, so many Chinese moved East (which is why you have historic Chinatowns in Chicago, NY, etc).
Editor’s Note: This is the second in a three-part series focusing on the expulsion of Chinese residents from Rocklin in 1876.
