A Quidditch match was played in 1385 in Lancashire by an Irish side against an English side, the first mention of Ireland playing Quidditch. The Irish players were run out of town after displaying skills with a Quaffle that had never been seen before (QA8).
The winning Irish team who played against Bulgaria in the 1994 Quidditch World Cup final (GF5, GF7, GF8, Pm) were Connolly and Quigley (Beaters); Moran, Mullet and Troy (Chasers); Aidan Lynch (Seeker); and Barry Ryan (Keeper).
- The 1994 team won while flying Firebolt racing brooms (PA4, GF8), the same broom that Harry Potter received as a mystery Christmas gift during his third year (PA11).
- One of Ron Weasley‘s saves for the Gryffindor Quidditch team was favourably compared to a spectacular save Barry Ryan had made against the Polish National Team (OP19).
- Aidan Lynch was fooled by Bulgaria’s Viktor Krum into a steep dive which ended in his being ploughed into the pitch. Lynch needed treatment for the resultant injuries during the match (GF8).
The players on the Irish National team that won the Quidditch World Cup in 1994 were all named after friends of J K Rowling (JKR).
Although Ireland won the 1994 World Cup and has a Quidditch team in the British and Irish Quidditch League, there is no mention of Quidditch or any other wizarding sport on their Wikipedia page (Wikipedia).
