Cook County Illinois marriage records show date of 25 Jan 1909 and Julia Ciralli
SS App for daughter Julia Catalano shows Julia Cirelli
SS App for son William Catalano show Julia DeLuca
However the California Death Index shows Joseph died in 1940. So by the time William applied for his SS#, perhaps Julia had remarried to a DeLuca and he put that on his app rather than his mother's maiden name.
