Friends and family of Mr O'Neill, who was from Belfast, have taken to social media to offer their condolences.
His cousin Mick Kerr wrote: "After a hard fought lot of days, you gained your angel wings. To most people we were just cousins, but to me, you were a teacher and the big brother that never took your eyes off me.
"We know your going to be watching over us all and helping us to get through the hard days and showing us the light to the better days."
One friend, Paddy McIlwaine, described him as a "gentleman" who you "couldn't say a bad word about".
