TJ and Adelaide were Australian wizards that found each other through work. TJ played seeker for the Wollongong Warriors while Adelaide was the manager for the Thundelarra Thunderers and they met after a game at a bar and hit it off. They started to date after that and 9 months later after their second date, Daku was born.
After few more years and a few more children, Blake and her twin Lillian were born, the last of the Lich children and TJ and Adelaide started to settle down, living in Wollongong because that was where TJ grew up and he and Adelaide wanted their children to grow up in Australia.
Kit had gone to the magic school in Australia for the first few years before the family decided to pack up their bags and move to England so the twins could go to school in Hogwarts. Kit was upset, he loved Australia and he had friends and was looking forward to living there for the rest of his life. The move to England was hard for Kit and made him bitter.
Once they got to England, Kit had to finish his last year of school in Hogwarts. He hated it, it was so awkward being the new kid yet you were a senior. No one knew him, and he was left to himself. He basically shut himself in at that and became just cold and bitter. He really hated Hogwarts and England and just everything. So what did he do? He ran away after he graduated.
Kit somehow managed to make it back to Australia unharmed after graduating Hogwarts. He got himself a job working at the local Aquarium with the dolphins and supporting himself. He was happy because he was back where he belonged, and you better believe he didn't miss cold and gloomy England.
Though after two years of being alone, Kit started to miss his family. Sure, they would send letters back and forth and keep in touch, but it wasn't the same as having them there in person. Though the loneliness soon subsided when Kit got into a relationship with Jennifer, she took away the emptiness and gave him a reason to keep going and not get down in the dumps.
They were together for only 5 months, but they were the best 5 months of his life. She was so happy and always smiling, bringing so much joy into his life. But it all came crashing down when she left Australia to go back to England, and Kit found out the horrible reality that she was engaged and was only using Kit to fulfill her desires.
After Kit got over the breakup, he decided he needed to be surrounded by his family. Especially after he found out that his siblings were already in their 5th year of Hogwarts and he had missed a good chunk of their lives. He didn't hesitate to pack up his bags and move to England this time around, finding a small apartment and settling in.
After being in England for awhile Kit met Seraphina Whiteford. She was a recent widow and was working in the ministry where Kit somehow managed to land a job as head of the department for the regulation and control of magical creatures. The two were friends for awhile before they decided to start dating, and one thing led to another and they got married.
Kit eventually left England during the year to go down to Australia and work, taking his step-son Lance Whiteford with him and then returning to England during the summers. After doing this for five years though, him and Seraphina both decided it was time for him to fully settle down in England and that's where he's been for the last year.
