Is anyone familiar with the name Jur (or Jure or Jura)?
Is this a Polish named that was used in Galicia, or perhaps it had a Jewish origin?

In particular I am wondering if it was a form of Yair (יאיר)  or perhaps it was short for Yeruchim (ירוחם) as in Yeruchim Fishel?

Any insights or experience with this would be appreciated.

Thank you.
