RE: Shady in Haiti 4 - The Order of Malta
Although I have my doubts on the names compiled by Eric Samuelson as being all Knights of Malta, it seems like Wikipedia's two pages list includes another name of interest to your post.
It is not mention in the man's main article, but Jimmy Savile does figure along these other names as an SMOM member. What his personal Wikipedia article mentions though:
Savile was honoured with a Papal knighthood by being made a Knight Commander of the Pontifical Equestrian Order of Saint Gregory the Great (KCSG) by Pope John Paul II in 1990. After the scandal broke, the Catholic Church in England and Wales asked the Holy See to consider stripping Savile of the honour. In October 2012, Father Federico Lombardi told BBC News:
[The Holy See] firmly condemns the horrible crimes of sexual abuse of minors, [and the honour] in the light of recent information should certainly not have been bestowed ... As there does not exist any permanent official list of persons who have received papal honours in the past, it is not possible to strike anyone off a list that does not exist. The names of recipients of papal honours do not appear in the Pontifical Year Book and the honour expires with the death of the individual.

The Pope meets Jimmy Savile in 1982.
Jimmy Savile: Catholic Church seeks to strip star of Papal knighthood (The Telegraph - 26 Oct 2012)
Jimmy Savile could become the first person to be stripped of a Papal knighthood posthumously after the head of the Catholic Church in England and Wales asked the Vatican to investigate removing the honour.
Jimmy Savile....nice find!
You're probably right about the list of members but I'm sure tha the list does in fact include many prominent figures.
Just like the vatican, it's not surprising that the Order of Malta has members engaged in child abuse and pedophilia.
My uncertainties with the names revolve mostly around the people with a jewish background, since it's a chivalric order for christians.
But everything is possible. In the names you putted out, those are on both web sites:
Some other names I recognized or of interest which are mentionned on Wikipedia's list, and who don't particularly appear as nobility at first sight (prior to the 1990s, all officers of the Order had to be of noble birth (i.e., armigerous for at least a hundred years)):
