It was "curioustrad"
He was actually a bishop, keeping a low profile and pretty much keeping out of the fray.
Apparently Fr. Joseph Pfeiffer went to him (among others) seeking the Episcopate, but since Bp. Fulham attended the same seminary at the same time as Fr. Pfeiffer, he "knew him too well" to want to consecrate him.
My understanding is that he was consecrated by sedevacantists (Thuc line), but he has since dropped that position. Hence his recent apostolate as "Fr. Fulham".
