Today’s names is a 14th C Czech masculine name:
As with many names from this particular source (and from this period more generally), this specific instance is recorded in Latin, which may disguise the underlying Czech form to some degree. (“Wr-” is not a common combination in Latin, so it’s definitely representing something foreign!) No obvious candidates come up in our searching, so we’re hoping that someone out there has a guess as to what name this might be representing! If you have any thoughts, please share them in the comments!
