Your dad was Voldemort aka Tom Riddle (he looks like the picture not ugly and noseless) you also had an older brother; Mattheo Riddle

Your father favourited Mattheo as he had always wanted a son, and not a daughter, not you.

He would always be cold to you and ignore you cause you were a girl. He wouldn’t care about you. Mattheo was his favourite and the only one that mattered

Your mother is Bellatrix Lestrange, and you looked a lot like her. Mattheo looked a lot like Tom.
