Mihaela Iliescu. A very interesting person if I may add. She was born and raised in Romania to a very demented couple. You see, Mihaela didn't get the pleasure of going to some primary school and the like. While little girls were learning about mathematics and reading, she was learning the art of deception, secret hording and evidence removal. While kids her age were learning about politics and history, she was learning about the inner workings of the infamous Underground. So no. Mihaela did not have a normal childhood.
As soon as she could form a coherent sentence, she became a cute and innocent accomplice. Basically, she would distract people by crying and calling out for her parents. That's right. Her parents would ditch her in Town Centers, Malls, Gas Stations just so they could rob somebody or something while they tried to calm down the hysterical girl. It was during one of these escapades that Mihaela proved that she was, in fact, a magical human being meant to bring peace and love to her family. I was being sarcastic. In all reality, she proved that she was even more of an asset to her parents. What happened? Well, she caused glass to shatter while she screamed "Mamă! Tată!" (Mom! Dad!). Of course, she had no clue what was happening which only made her cry harder.
You could only imagine the little pathetic light bulb that went up in her parents heads. They used this occurrence to their advantage. Oh, and before you ask, her parents just so happened to be a wizard and witch in hiding. Hiding from what, you ask? Let's just leave it at prison. Back to Mihaela. Her parents decided to use her newfound magical abilities to their advantage. They'd get her wound up, to the point where she was hysterical and cause major distractions (you know, exploding windows and all that), which allowed them to steal whatever they wanted.
Mihaela eventually got her letter to Durmstrang and immediately her parents sent her there. After all, she had to learn how to control it. How else where they to teach her potent spells? What they hadn't counted on, was their daughter to come back strong-willed and cunning. You see, all they saw was a tool. They never saw the flashes of rebellion in her eyes, or the subtle ways she was able to make those around her be enraptured by the little red head.
Of course, they were immediately pleased when they saw that she was even better at getting information then they thought. They had invertatly raised the perfect little spy. How? Well, Mihaela picked up on quite a few things. Simple things. While her parents stole, she learned how to listen, how to keep up an act, how to get people to trust her so completely that they'd never suspect a thing. She learned how to read people. And it's all thanks to her parents constant abandonment.
When she graduated, she immediately disappeared. Her parents thought she died. Her 'friends' thought she went to America to be with a foregin lover. Both are very wrong answers. Mihaela disappeared to England, where she heard from the rumor mill that there was a better place for criminals artists like her to dwell. To grow. To learn. And that she did.
