What is "muire"

Muire is an Irish name given exclusively to the Blessed Virgin Mary. The Irish name Máire is typically used for the name Mary. Muire is used exclusively for the Virgin Mary.

The only known exception to this rule is in the song Caoineadh na dTrí Mhuire , in which the three Marys present at the crucifixion speak their thoughts. The name Muire is used so as not to give the Blessed Virgin Mary a common name.
