This image from a 1939 publication comes courtesy of Dave Beck. The lower photo, taken in 1917, shows Cino Cinelli in the arms of his mother. Cino's older brother, Giotto Cinelli, is in the middle next to their grandmother. All the Cinelli siblings are named.
The article also mentions that Giotto Cinelli owned a plastics factory at the time.
