"first black J. G. Jones to become a recognized member and position holder of UGLE" there are and have been thousands of non-white members of the UGLE btoh here in England and wales and obviously in our District Grand Lodges around the world. - I understand that the UGLE membership is diverse, but my question is really if the UGLE has placed a member of a body that it does not recognize as a "position holder" within it's ranks.
"suggesting that he is a "recognized Past Provincial Grand Master of London the East Lancashire District" There is no such term or rank under the UGLE. I can give you a fuller explanation of why if you need it. - For the purpose of passing complete and accurate information along, I would like some additional explanation, if you don't mind.
"first black John G. Jones Freemason to be recognized as a Grand Master in the history of the UGLE". I am able to confirm that there has not (yet) been a black Grand Master, however, there have been many black, asian and hispanic District Grand Masters - I believe that he is referring to recognition that he is a GM over here in the U.S. He isn't saying that he is a GM in the UK. I know this is very confusing, but it is an epidemic that various Prince Hall jurisdictions deal with everyday.
