Every Monday we will post an entry that hasn’t yet been published with a view towards harnessing the collective onomastic power of the internet. If you have any thoughts about the name’s origin, other variants it might be related to, other examples of its use, etc., please share them in the comments! If you wish to browse other Mystery Monday names, there is an index.
Today we’re giving you not one, not two, but three mystery names! Why three? Because there might be a chance that they are related to each other. All are masculine names found Switzerland in the 14th-15th C; one is recorded in Old French, one in Latin, one in Middle French; all start with Cuen-.
Of the three, Cuenod is the easiest one to analyse: The -od suffix is a common Swiss diminutive suffix (cf. Perrod, Johannod, and others). If we take -in and -zy as diminutive suffixes (plausible in the case of -in, as it shows up in French; -zy is otherwise unfamiliar to us), then the root is Cuen- — possibly from Cuno or Conrad?
What do you think? Are we barking up the right tree? Have you any other examples of these names, or of names that might be related? Have you ever seen -zy as a diminutive suffix before, in Switzerland or elsewhere? Please share in the comments!
