Joyce, I did find Arpers in the San Francisco 1882 & 1890's San Francisco City Directories. They were not listed in the 1887 San Francisco City Directory. From 1882 San Francisco City Directory page 172: ARPER Clarence T., compositor, r. 806 Green ARPER Thomas, engineer Cal. Wire Works, r. 806 Green ========================================= From 1890 San Francisco City Directory page 155: http://www.sfgenealogy.com/php/1890.php?page=155 Sorry, the 1880 McKenny's Pacific Coast Business Directory does not list any Arper's in Alameda County. http://freepages.genealogy.rootsweb.ancestry.com/~npmelton/pcd_indx.htm Nancy Pratt Melton Golden Nugget Library npmelton@yahoo.com http://freepages.genealogy.rootsweb.com/~npmelton/index.html
