Connor James Gallagher was born on April 2 to Abigail and Brennan Gallagher in Mullingar, Ireland. Abigail and Brennan had met about ten years prior to Connor's birth during their 6th Year at Hogwarts. Abigail was a Ravenclaw whereas Brennan was a Gryffindor. Believe it or not, the pair hated each other at first. Abigail thought Brennan was obnoxious and immature, and Brennan thought Abigail was uptight and stuck up. It wasn't until their 7th Year that the tension became too much and they began dating, much to everyone's surprise. Afterall, opposites do attract.After graduating from Hogwarts, the couple decided to buy a small flat near Hogsmeade. Abigail was quick to get hired working in the Department of Magical Education in the Ministry of Magic and Brennan went to play Quidditch as a chaser for Puddlemere United. Life was going smoothly for the pair and they went about 8 years living together before finally deciding to start trying for a child.
It ended up taking almost a year until Abigail finally fell pregnant with her soon to be born son. Sure enough, 9 months later Abigail gave birth to Connor. Not even 2 years after Connor was born did his younger sister, Bedelia, come. 2 years after Bedelia and the triplets, Rowan, Fiona, and Myles, were born. Just as the large family thought they were done, Abigail became pregnant with her final child, Kira.
Abigail ended up quitting her job at the Ministry to raise her children until Connor was old enough to take responsibility so she could go back to working to help provide for her family. Being a professional Quidditch player, Brennan had a fairly large salary but was often gone playing games.
Connor was only 7 when he showed his first sign of magic. He grew up with knowledge of the Wizarding World as both his parents were Hogwarts graduates, so it wasn't much of a surprise when he found out he was a Wizard. Connor was stuck babysitting the triplets one night as his parents had gone out with Kira and Bedelia was having a sleepover with one of her friends. The triplets were toddlers at this point, and Connor couldn't get them to do anything he asked no matter how hard he tried. Eventually he got them to all sit down on the couch together and just as they were about to run off, they couldn't leave their seats. Connor had unintentionally glued them to the couch so they wouldn't run away. While Connor was pleased he no longer had to chase after them, his joy didn't last long as they immediately began screaming and crying.
Upon the realization that Connor was a wizard, Brennan decided to teach him to play Quidditch. Connor had always been an athletic child having taken up other Muggle sports like football (not the American version), tennis, and rugby. He was never afraid to get down and dirty which is probably part of the reason why he is so good at Quidditch. Not only is athleticism in his blood, but he wasn't and still isn't afraid to sacrifice anything to win a game.
Connor was sorted into Ravenclaw upon arrival at Hogwarts. This was no surprise as he took after his mother's wit and determination. Connor decided to try out for the Quidditch team and, to his great surprise, made it on as a beater his first year. As he got older and his years continued at Hogwarts, he eventually started playing Keeper instead as he had the build of a phenomanal keeper. Connor did extremely well in school aside from Quidditch and managed to graduate with all O's and only one EE in Divination.
After graduating school, he initially set out to get a job as an Auror, however quickly realized this wasn't the right profession for him. He decided to take up Quidditch professionally and play on the Kenmare Kestrels as their keeper. Connor played for the Irish team for about 7 years before being recruited by the Irish National Quidditch Team where he as remained ever since.
