Regarding Detroit, there are no third generation Giacalone's. However, the second gen Giacalone clan ages range from 40's (Vinnie Jack), to the 70's.

Jack and Anthony Tocco's sons and nephews make up a significant portion of the active made men.

Another historic family in Detroit that is little talked about is the Corrado's. At least six of third gen Corrado's are made. Just like the wedding scene in GoodFellas, most of them are named Peter and Paul, so it is sometimes difficult to differentiate them lol
