I was able to locate my grandfather Gilbert and 4 of his brothers at the Ancestry website.  To view what I found, log in if you have an account.  Enter the state of Illinois, the county of Cook, and the city of Chicago.  Scroll to district 103-1577.  At the top of the page you will see page 1 of 24.  Use the right arrow to take you to page 11.  Joe is on line 22 and Gilbert is on line 24.  Henry (Hank) is on line 28, Paul is on line 31, and John is on line 32.

Scroll to the bottom of the census to see that Anna Del Principe (line 29), Hank’s wife, was asked supplemental questions in this census.
