Obviously, I couldn't sleep last night, because I found some more!
The WWI registration cards show Charles Sr. born Nov 9, 1872, and Charles Jr. born Feb. 12, 1894.
In the 1920 census Charles Jr. has been married for 1 year to -- you are never going to believe this -- Annastacia! So not only did your family have 5 Charles persons, they apparently had 3 Anastasias at least. But the last one went by Anna in the 1930 census, thank goodness.
In 1918 Charles Jr. was working for the Goodrich Transi Co as a Marine Engine oiler. The company was based out of Chicago, but his home address is still the 1100 S 7th address.
