The Belfrey family has had their fortune for a long time now, for as long as the records have kept track of them. The Belfreys are known for birthing children who grow and branch out to become some of the most productive members of society, as entrepreneurs, lawyers, healers, government officials, etc. Over time, they've come together and amassed an unimaginable wealth, to which every Belfrey now has access to, contrary to the times where only the men in the family had access. Though they've always been centered in France & the United Kingdom, you're likely to find a descendant of the original Belfreys wherever you go - granted you know where to look. Lord knows the Belfreys breed fast, and at great quantities.
A key component of their family is the way they've come across throughout time. They're one of the original families in the world of magic - they've been in this Earth for centuries now, and thus feel a sense of superiority. It's not so much because they're of pure status - that's far from it. They've seen the rise and fall of many legendary families, great wizards and witches coming and going simply because they saw themselves as the best of the best, just because of the purity of their blood. That doesn't take away from the fact, though, that not all of them share the same mindset. Now think about how difficult it must be, living with a family that's ethically & morally diverse. The current Belfrey patriarch is a blood supremacist, despite his inclusive upbringing. He lived around the era of the Great Wizarding Wars, and has clung onto old ideals as an (undiscovered) former Death Eater. That, in itself, is bad enough.
His eldest daughter, Victoire Belfrey, is a prideful, arrogant woman. She strives to be one of the most powerful, one of the richest and most beautiful women to grace the British wizarding society. She's an over-accomplisher who married into the Yaxley family - a family known for their purity, their stance on muggle-borns and creatures, and the sheer amount of influence they have, what with all the political figures and lawyers they've spawned. Victoire is easily one of Bartholomew's favourite offspring; she understands what power is and strives to have it all. For that reason, her children's upbringing involved awareness of their status, and subsequently loads of tutoring on proper etiquette. They are, suffice to say, modern nobility - they have been ever since the rise into power of the Magical Monarchy. They need to look and act the part.
Ethan was a terrible child to be born into the Belfrey's. He paid little attention to the upbringing, preferring to throw himself in the world outside, exploring every nook and cranny in the lavish gardens that he could find. On the rainy days, Ethan would spend his time exploring the house, trying to find secret passages. He'd often employ his siblings to play hide and seek with him or act in some game of make believe. Ethan loved animals and often begged his parents for them. By the time he was ten, he had a small zoo of dogs, cats, rodents and even a docile snake. Guinea pigs were his favourite. Ethan was also fascinated with ancient history, though. Ethan use too beg his parents to take him across Europe and Egypt in search for ruins. Ancient Roman, Greek, Mesopotamia, Egypt–all were things that Ethan loved to read about. Ethan was always over the moon when he was allowed to visit a site with either one of his parents or a trusted employee or friend. Ethan's fondest memory as a child was visiting Hadrians wall in England. Ethan had little mind or care to the noble aspect of his family. Ethan's dream was never to be a gentleman who spent his time at some dinner party or other. He didn't really want to be involved in the ministry. Because of this, his parents were often frustrated with their son. Ethan didn't want power, he didn't care for blood supremacy, he didn't even seem to care for his surname and the influence it gave him. All Ethan wanted was information and the ability to explore history, as well as spend a chunk of his time with animals.
It was because of this optimistic and carefree attitude that made him almost shrug off his older sister's reveal of only being his half sister. Colette was half nymph with a different father. Ethan was always closest to her, always made her the victim of his silly games. Ethan use to beg Kohl to be his partner in exploring the house and grounds, even when they went through that part a hundred times over. When her powers began to shine through, it was only their parents severe attitude that caused Ethan to distance himself. He was a child and was rather intimidated by his parents, especially when they spoke about Kohl. However, the moment the parents were gone, Ethan ended up running back to her. How could he shy away from the only sibling that really put up with his nonsensical games? Being as young as he was, Ethan didn't truly understand why so many of his family had a problem with her. When he was nine years old, he had his first magical experience. Ethan had this little figurine of a mummy and one night he caused it to come alive, making it walk around. It delighted Ethan and he didn't stop raging about it for weeks.
Ethan was sorted into Gryffindor when he was sent to Hogwarts at age eleven. Ethan didn't mind Hogwarts. He had neither a good experience or a bad experience. It was simply school. Ethan had a few friends but he much preferred to spend his time in the library, pouring through history books. Ethan was really written off as a bookworm but he was likeable enough. Ethan always had a good attitude to everyone he met and this translated well with how Ethan interacted with the world around him. Ethan was someone you could get along easily with and was always there with a smile. By the time he was sixteen, Ethan had almost rejected his parents values, becoming open minded and always pushed for inclusivity. Of course, he never rebelled against his parents. Ethan kept his mouth shut when they went on their tangents, maybe throwing in a light hearted comment here and there that often bothered his parents. In fact, he reached a point where he never took his parents that seriously.
When he was eighteen, he decided to travel. Ethan wasn't too sure what to do with his life. His parents wanted him to go into the ministry but he didn't want to. Politics wasn't for him. So he went travelling. For years, he rarely came back to England and spent his life travelling from country to country. When he was nineteen, he settled briefly in America, becoming a cursebreaker for their government there. During this time, he rarely called his family save for his siblings. His relationship with his parents had broken down when they realised Ethan was never going to be the son they, specifically Victoire, dreamed about. However, now twenty one years old, he was finally coaxed back to England. He had gotten wind of the new policies in place and decided that it was time to return and try to help out where he can, particularly considering his sister would be affected if it were to be discovered that she was part nymph.
