<Li> Da (Tim McGarry) - He is an Irish Catholic who represents a stereotypical Irish nationalist . He believes very much in Irish culture, despite the fact he admits he cannot speak a word of Irish . He is a Sinn Féin spokesman (later an assemblyman) and prides himself on his' friendship' with Gerry Adams, trying to copy his outward appearance by wearing a beard and glasses . Da is shot and killed by Ma and Dympna in the last episode after it is revealed he prevented Liam Neeson from proposing to Dympna and was suspected by Ma of having an affair with a woman named Siobhan, who also tries to kill Da, but misses . Da lived in the Divis Tower on the Falls Road . It is suggested that he was in the IRA even after becoming a Sinn Féin member, considering that in the 2016 special "The Farce Awakens", Ma claims that he was wearing a balaclava when she met him, and that "when he says' the boys', he means the Ra". </Li> <Li> Cal (Damon Quinn) - Although he is a grown up man, he still lives at home and often behaves like a child . He supports his father in the struggle against the British imperialism and does whatever Da tells him, no matter how daft . In the pilot "Two Ceasefires and a Wedding" he is portrayed as a sinister Irish Republican Army activist . In the series however, his character is dumbed down and he is the "thick one" of the family . At the end of the series he falls in love with Siobhan, a Protestant woman who had previously posed as a Republican to get closer to Da, who she was madly attracted to . </Li> <Li> Uncle Andy (Martin Reid) - An old - fashioned traditional loyalist whose twin loves are British Ulster and Elvis Presley . He is very argumentative, and determined to take offence at even the mildest suggestion that anyone in authority is trying to oppress him . He often devises elaborate political or moneymaking schemes with the aid of Big Mervyn, but owing to their shared lack of intelligence or foresight, these inevitably fail . Andy is shot and killed by Billy in the last episode after it is revealed that Andy and Mervyn had been taking out huge loans in Billy's name, eventually leaving him penniless . </Li> <Li> Billy (Michael McDowell) - Andy's nephew and an RUC (later PSNI) officer . He fell in love with and married Emer (and later Dympna). Throughout the series' life, there have been occasional hints that Andy may be more than just his uncle . In the 2003--2004 series, however, the writers knowing that they couldn't keep up that pretence for too much longer, the story was finally "wrapped up". In the final episode he murders both Uncle Andy and Mervyn, but receives a pardon from Martin McGuinness and Ian Paisley . He then commits himself to clearing Dympna's name, despite being shacked up with two other women . </Li>
