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’s name is so mysterious, we’re not even sure what gender it is. Grammatically, it looks to be feminine — it’s recorded in Latin and ends in -a in the nominative, which tips the evidence in favor of a feminine name — but the context provides no clear indication of the gender of the bearer, so we are still listing the gender as “unknown”.
It does appear to be a diminutive, with -ca or -ka being a moderately common feminine diminutive suffix in Slavic contexts, but what the root name might be, we haven’t a clue. Do you? Please share your thoughts in the comments!
