If you want to be sure that your donations go to Bishop Williamson the best way to do that is through the St. Marcel Initiative:
http://stmarcelinitiative.com/As for which priests are connected with Bishop Williamson, the answer would be, any good ones. I think that it would be hard to make a list with all of them, but perhaps we could all add those we know here, and someone could compile that list?
For my part, I know that the priests at my chapel support him: Fr. Ringrose, Fr. Ortiz, and Fr. McMahon.
I believe that Fr. Collins from New York was also in good standing with him last I knew.
In Australia there is Fr. Chazel, and Fr. Edward who is supposed to be there soon.
So, that is six from me. Anyone else? :-)
