Trying to get this straight. We know that four ceremonies have taken place since the millennium. One shortly after the Casasanto hit (so around 2004ish), one in 2007, one around 2011 after Steve Mazzone cleared his parole restrictions and one in 2015. Here is the list of guys mentioned as new members since this period:

Damion Canalichio (made around 2004, identified in the Licata detention memo)
Martin Curro (identified on a Philly PD mob chart from 2009, perhaps made in the late 1990s)
Frank DePasquale Jr (identified as a member by a Philly PD officer during the Ligambi trial)
Eric Esposito (made in 2007, identified in the Licata detention memo)
Louis Fazzini (made in 2007, identified in the Licata detention memo)
Domenic Grande (identified as a captain by GA and DS)
Albert Lancellotti (identified as a member by CW Michael Orlando during the Ligambi trial)
Salvatore Mazzone (identified as a member in court documents from Lucibello’s parole violation)
Anthony Nicodemo (made around 2004)
Anthony Persiano (CW)
Salvatore Piccolo (indicted as a member)
Joseph Servidio (indicted as a member)
Anthony Staino Jr (identified as an associate in articles from the early 2000s before identifying himself as the ‘CFO’ of the mob in wiretaps from 2004)

2004(ish) – 5 guys made (Canalichio, Nicodemo + 3 others; likely Staino, DePasquale and Lancellotti)
2007 – 2 guys made (Esposito and Fazzini)
2011 – 3 guys made (Grande, Mazzone and Servidio)
2015 – 5 guys made (unclear)

Persiano and Piccolo were likely made at a different time or perhaps transferred from the Lucheses after the whole debacle with Scarfo Jr attempting to take over Philly.

Possible Members:

Anthony Accardo (indicted as an associate in the Merlino trial, rumoured as being made in 2015)
Joseph Baldino (rumoured as being made in 2015)
Joseph Bongiovanni (rumoured as being made in 2015, died in 2017)
Anthony Borgesi (identified as a proposed member in the Licata memo, rumoured made in 2015)
Vincent Grosso (rumoured as being made in 2015)
Philip Ligambi (possible member, made either in the 1990s or 2004)
Vito Malgeri (identified as a proposed member in the Licata memo, rumoured made in 2015)
David Salvo (rumoured as being made in 2015)
Michael Salvo (rumoured as being made in 2015)

Obviously not all of those individuals were made in 2015. Since no credible information has come out as to other induction ceremonies during this time it seems like at least three of the names above are not members.
