There have been fewer cardinals in the Church from the Order of Canons Regular of Prémontré (aka Norbertines) than there have been of other orders and, as far as I can tell, two of those known to be associated with that Order were Abbots in Commendam only. The Premonstratensian Cardinals are:
Armand Jean du Plessis, Duke de Richelieu, Bishop of Luçon, Commendatory Abbot of Prémontré, (also Territorial Abbot of Cluny and Abbot in Commendam of Citeaux)
Johannes von Bucka, O.Praem. Archbishop of Olomouc
Ippolito II d’Este, Archbishop of Auch, Archbishop of Arles, Commendatory Abbot of Prémontré
EXARANDORUM 
Was the Duke de Richelieu an Admiral of France. The anchor seems to say that, although for a bishop and abbot it would be strange.
Yes, he was. He held the title “Master of the Navigation” from 1626-1642. Since he was also the First Minister of State it really wasn’t that unusual despite his being a clergyman.
wow, a lot of quality images, i really love this place
