Originally from Chicago, Illinois, Vivian and her mother moved to London when she was ten, in order to follow an employment opportunity for her mother. Vivian's mother works as a Muggle model for high-end fashion. Vivian's father died in an automobile crash when she was just four. Her father, David, and her mother, Emma, were on the way to their OB-Gyn to check on Emma's pregnancy. She was pregnant with Vivian's younger brother, Cyrus. David was the Wizard of the famiy. In this crash, both David and Cyrus died in this crash.
Robert and Emma met on a tour of Chicago. Emma is originally from New York City, but moves around quite a bit for her job. They fell in love, and it wasn't long before baby Vivian came along. After Vivian arrived, Emma and David stayed together. Four years later, things were still going well. But then, the car crash happened. At this time, Vivian was around four. A few years later, Vivian was eight, and was growing up a cute child. However, at this time, Vivian started exhibiting signs of magic. At first, Emma was confused, then realised that it was only Vivian showing signs of magic, like her father before her.
The first signs were only a few breezes where there shouldn't be any, but when Vivian was nine, her mother dropped a book and it made a very large BANG! As this happened, there was a huge, blinding flash of light, and the temperature went down about a dozen degrees Celsius. Emma gasped and looked around, suddenly chilly. Vivian gasped and whined, "I'm sorry momma! That just scared me!"
This sign came shortly after Vivian's mother moved their little family to London in order to follow a new modeling opportunity. Emma's agency in New York opened a London branch, and Emma decided that volunteering to start in London was what her family needed. A fresh start.
After Vivian started school, Emma became a bit distant. Though Vivian was growing into a powerful young witch, Emma wasn't there to see it very often. It may be that, while Emma was okay with Robert being a wizard, it wasn't really real for her until her daughter exhibited signs of magic as well.
Watching her mother become distant really shut Vivian off to the world. She started becoming colder and more isolated, wanting only to further her own goals. Around Vivian's third year was when she learned of the existence of Dark wizards. By the time fourth year rolled around, Vivian had decided that she wanted to learn Dark magic. What her parents and family would not give her, she would take by force. After all, those that could not hang on to power, did not deserve to have it at all.
Vivian has very recently finished a personal research project. The project was tracing her own family ancestry. It ended up leading to a very odd and somewhat familiar place. Hungary, and the royal families of Central Europe.
Though Vivian never believed her mother when she had said that Robert had 'the blood of kings'. it seemed that she may have given her mother too little credit. The Hecc family appeared to be descended from the Ecsed branch of the Bathory family, who were nobles under King Albert of Habsburg. Later came the infamous Bathory, Elisabeth. She was the uniting piece of the two branches of Bathory, Ecsed and Somlyo.
However, there was evidence to suggest that Elisabeth had had a few children, and her paternal grandmother wrote to her that they had evidence of that. She claimed that they would tell Vivian all there was to know after she graduated Hogwarts.
This being said, if her grandmother does have the evidence that she suggested, it would place Vivian much closer to the current Habsburg family. However, we shall have to see.
