Possibly a term for heraldic or decorative patterns featuring ermine, or a medieval guild/occupation related to ermine fur trade and tailoring.
From 'ermine' plus a suffix suggesting a group or profession (potentially '-ites' as in 'people who work with ermine'); this term is rare and may be specialized heraldic vocabulary.
This word is so obscure that it barely appears in historical records—it might be a lost medieval occupational term for ermine merchants or furriers, one of thousands of medieval jobs that completely disappeared when their industries changed.
