While neither of these abbots was elected very recently, within the last year there were two new Premonstratensian (aka Norbertine) abbots elected and blessed in the USA, one in Wisconsin and the other in Pennsylvania.
The Rt. Rev. Dane J. Radecki, O.Praem elected on April 4, 2018 as the VII Abbot of St. Norbert Abbey in DePere, WI. He was blessed on July 11, 2018.
The Rt. Rev. Domenic Rossi, O.Praem, elected on January 23, 2018 as the IV Abbot of Daylesford Abbey in Paoli, PA. He was blessed on April 14, 2018.
EXARANDORUM 
There is an interesting detail in the arms-RADECKI: in the dexter half, for sure the symbol of the abbey, we see four sheepscissors (I don’t know the english word) and the saltire. They are together the coats of arms of the Lords of Gennep, south from Nijmegen, in Dutch-Limburg. S. Norbertus, the founder of the Norbertines, is the son of Lord Heribert of Gennep. The only question that rises is why the field behind the saltire is not gold, as it was in the coat of arms of the Lords of Gennep and in the later municipality of Gennep.
Up to me the medal in the arms ROSSI is an unheraldic element and diffucult to see.
The shears are from the arms of the house of Gennep. They were not attempting to recreate those arms but allude to them which is probably why the field is argent rather than or.
DOES THE HEAD OF THE SULPICIANS HAVE A COAT OF ARM? IF SO WHAT IS IT?
