Today’s name is an odd little one. We’ve got four different grammatical forms of the name, which all occur in the same charter in reference to the same person. All the documented forms spell it with initial Y-, but since Y forms are always atypical we have hypothesized a standardized form with I- — but it is definitely nothing more than hypothesized!
The record comes from Tirol, and many of the other names in the same source show distinct Germanic influences, so it would be reasonable to look to Germanic origins as well as to Romance. On the Germanic side, the name could be related to Old Saxon, Old High German īsarn ‘iron’, which does show up in names in the form iren. But is yran a reasonable extrapolation from iren? We’re really not sure.
And we’re even less sure what a possible Romance origin of the name could be.
Do you have any thoughts? Seen any other examples of this name? Please share in the comments!
