Hello. I have, with help, followed a path that I believe to be that of my Great Grandfather, Pietro/Petro/Peter (Adolphus?) Lusardi/Lucardi who left the UK in February 1906, arriving in New York 25 February 1906. I think he moved to San Francisco and was a lodger in Colton Street on the 1910 Census. My next record is of the death of Pietro Lucardi on 10 Feb 1918 from the California Death Record. I don't know where to go next. I can't seem to fill in the time between 1906 and 1918 and would like to try and find out more about his life and death in general. Any suggestions would be gratefully received. Thank you.
