Donny Maguire is one of the least seen of the Maguire sons (besides Joey and possibly the late Fergal), that appeared in the early series. His first appearance in Series 1 (only credited as Maguire 1) involved him and two other Maguire brothers, forming a lynch mob after Ian, in revenge for trying to force himself on Mandy. However Mandy had lied to them, Ian had offended her by doing the opposite, and been unable to have sex with her due to being secretly gay. Donny later appeared again in Series 2 (now credited as Donny, as well as named on screen by his father) as part of the Maguire family, during their initiation of Ian into their clan, who they believed to have inpregnated Mandy. Donny later appears in Series 3, this time twice. In one episode, he joins his father and his two brother
