Roin
Its likely root is Persian, "brass" or "copper", carrying the sense of "brazen", though Polish sources don't confirm it. A rare name here: only about 100 men carry it, and most Poles have never met one.

What Roin means
Where Roin comes from and what it has meant to the people who carry it.
The name Roin traces to Persian, where rōīn means made of brass or copper. Ferdowsi's Shahnameh gives the epithet Rōīn-tan to the hero Esfandiyar, the warrior whose body was brass and whom no weapon could pierce. His one weakness was his eyes, and there Rostam's arrow found him. The short meaning recorded here, brazen, holds the older sense of the metal rather than the modern idea of nerve.
In Polish sources the name is not attested. It has no imieniny, no settled diminutive, no counterpart across genders.
Picture a September morning and a teacher working down the class register, pausing at Roin before the next name. Then the roll continues. The meaning stays close to the metal: brass, the alloy that in one Persian tale gave a hero his unbreakable skin.
