Oisín was rushed to hospital on Monday afternoon and placed on life support, but tragically died three days later. Having passed away in the Royal Victoria Hospital in Belfast, Oisín's body was brought home to his hometown of Belcoo on Friday.
Oisín's parents Sharon and Nigel lead the mourners at the 11am funeral mass in Co. Fermanagh.
Speaking about Oisín's kind and unassuming nature, the funeral celebrant Fr. Séamus Quinn said: "While Oisín was a leader…he wasn’t in love with the position of leader and, in fact, Oisín would always take time and make place for people who might not have found it as easy to achieve as he did himself."
Stories of Oisín's mischievous nature were remembered as heartbroken mourners learned that the young teen had recorded himself playing the violin on his iPod and in a bid to get out of practising he would play the recording over and over in the hopes of fooling his family.
Turning his attention to Oisín's parents, Fr. Quinn said: "The flame of your spirit must waver at times in the face of it all…know that your young saint, Oisín, who never did anything bad or evil in his life, but consistently did everything he could to show gentle love to those around him, will be with you to accompany you in the time to come."
The young teen, who was described as generous, helpful, giddy and funny by heartbroken classmates, has saved five lives by donating his organs.
A GAA football jersey was draped over Oisín's coffin as the funeral cortege made its way past grief-stricken mourners this morning.
