The Bonannos had ceremonies in 2001, 2003, 2004, 2005, and 2008. No doubt more since then.

The Colombos in 2000, 2004, 2007, 2009, and 2011. No doubt more since then.

The Luccheses in 2000/1, 2003, 2005, and 2007. No doubt more since then.

The Gambinos in 2001, 2003, 2005, 2006, 2007, and 2008. No doubt more since then.

The Genovese in 2000, 2003, 2006, and 2009. No doubt more since then.

I think it's probably a safe bet the NY families have one or more ceremonies every year. The years listed above are specific ones that have been cited though.

The DeCavalcantes supposedly made 12 new members between 2001 and 2006. Not sure about after that.

Philadelphia in 2005, 2007 and 2011 - at least 10 new members have been made over that time.

New England in 2002 and possibly 2006. Not sure about after that.
