Erin Quinn is the best friend of Clare, Michelle, James, and Orla.


Erin lives in Derry with her mother Mary, her father Gerry, her sister Anna, her aunt Sarah, her cousin Orla and her grandfather Joe. She attends Our Lady Immaculate College. Erin was born and lives in a time of religious and national conflict called The Troubles.

Erin has grand ambitions to become a famous writer and has serious ideas above her station. She considers herself to be very liberal and worldly; in reality, she's quite easily shocked and has never ventured further than Buncrana (a popular holiday destination).


Erin describes herself as creative, favors writing, and keeps a diary. She thinks of herself as a deep and liberal individual. She can become awkward in some situations, especially those that involve boys. She is a caring person but can be a bit highly strung. Erin can occasionally appear narcissistic interpreting situations from only her point of view. This sometimes impacts her personal relationships, periodically.

She is very goal-driven and a fan of the English boy band Take That.



She had a crush on David Donnelly and would embarrass herself when he was around.

She flirted with Dee, but her interest wasn't reciprocated.

She attended the prom with James Maguire after her original date, John Paul O'Reilly, didn't show.



She is friends with Orla, James, Michelle, and Clare.



Notes and TriviaEdit
