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 an unusual one — a feminine name found in 14th C Münster, Germany, which is not an immediately recognizable saint’s name or clearly of Germanic origin. We have also extrapolated the header form, working from the general principle that “I” is more common than “Y”. Nevertheless, this is just a hypothesis at the moment, and we would welcome evidence showing that Yslana is a more suitable standardized form — or indeed, any information or further evidence concerning this name.
Do you recognize the name? Have any thoughts about it? Please share in the comments!
