- "This warrior bows to no king."
- ―Sheamus Cassidy
Sheamus Cassidy was born in Dublin, Ireland on January 28, 1983 to Maeve and Sean Cassidy. Sheamus was raised in Dublin by his parents for about the first ten years of his life, being very much into football, rugby and wrestling.
In 1993, Sheamus and his infant sister Theresa, went with their mother to visit relatives in Armagh in Northern Ireland. While she was there, Maeve, an innocent bystander, was killed by an explosion caused by terrorists. No trace of Maeve was found by the authorities, and they and Maeve's relatives, assumed that Theresa and Sheamus had also been killed in the explosion. In fact, however, their uncle, Tom Cassidy, had been present at the scene of the explosion and secretly helped save Sheamus and the baby.
