Perot de Garbalei, flourished circa 1300, is only known as the author of one poem.
All the geographic information is found in well-known earlier Latin works.
[1] Perot states that he "read a very learned book in Latin which many clerics said could not be translated into vernacular rhyme".
On the basis of his name, he may have been from a location called Galbally, i.e. if Garbalei is a variant of Galbalei.
Several villages or townships in south Wexford bear the name Galbally.
