I just took a look, t appears that the more specific word Presbyterian is from the 17th century.
In Harley MS 560 (12th century), the term "presbiter cardinalis" is used many times for different people.
The only reason this even occurred to me (to read prbren as presbyteren) is that I see the abbreviation for presbiter/presbiteren frequently in manuscripts. Not as often as the abbreviation for sanctus (which is extremely common), but nevertheless, quite often. It's abbreviated in numerous ways.
