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.
Here’s a poser! By the 13th century, there aren’t that many names of Germanic origin where the root themes are obscure. And yet, this appears to be what we have here. This masculine name found in 13th C Switzerland is probably of Germanic origin, with the final element being Old High German, Old Saxon gēr ‘spear’. But what on earth could Elisa- be? This is one of those names that is quite opaque to use, and we would love any insights or thoughts you might have. Please share in the comments!
