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 found in Old and Middle French and is a strange example of a name that we don’t have any Latin instances of! It’s probably of Germanic origin, with the deuterotheme being derived from Old English heard, Old Saxon hard, Old High German hart ‘strong, hard’. But that being said, we have no idea what the prototheme could be. Do you have any thoughts? Please share in the comments!
Also, while not entirely relevant to the onomastic question, we did find a cool titbit about a historical Chiquart: one “Maistre Chiquart” as cook to the Duke of Savoy, and author of a cookbook, Du fait de cuisine.
