He was born in Athlone, The Rebublic of Ireland, on February 7th, 1990. He has a channel on YouTube which is very popular along the ages of 10-14. He goes by "Seán" in his day to day life, and "Jack" when he is online. Lots of his community on his channel ships "Septiplier" which is a fight over if Jacksepticeye and his fellow friend, Markiplier should be a couple. (I ship it) Mark and Seán record videos together and joke about their ship. They are very cute together and i love it when they blush when certain things are said.
