I must admit that I do not celebrate St. Patrick's Day, even though my maternal grandmother was from Ireland. I do take a few minutes on March 17 to honour her. She was a vital part of my childhood and a kind and caring person.
I celebrate my Irish ancestry on February I, Imbloc or Brigid's Feast. The following links are provided for those, who are interested in learning, about the customs of the Ancient Celts, who were among the early inhabitants of Ireland, Scotland and Wales.
