“Pine St originally consisted of two sections, Abbot and Kelly’s St, which were both renamed in the early nineteenth century”

Pine is translated as Giúis (tree = Crann Giúise) or Péine. Abbot is translated as Ab.
I cannot find any reference to Phaghanaigh in the dictionary. Págánach does translate as Pagan or Heathen.
