Hello, I am new to the list and just discovered some relatives (Azores) who were naturalized in San Mateo County before 1905. I always thought their naturalization would have been in San Francisco and therefore a "lost cause". Can someone post if they know what records and indexes are available for the Superior Count Naturalizations and WHERE those records might be located. I am located in Southern Cal but do travel north several times a year. Thank you Lisa Harley La Crescenta, CA
