Matthew Maddox Jr.

Matthew Connor Constantine Maddox Jr. (born 21 February, 1983) is an English pure-blood wizard and the first son and third child of Matthew Maddox, Earl of Dartmoor and Máire Maddox (née O'Sullivan), Countess of Dartmoor. He is named after his father and he is the current heir to the title of 'Earl of Dartmoor'. After his grandfather's death in 1983, his father succeeded him and became the Earl of Dartmoor along with his mother as the Countess of Dartmoor. Subsequently, he became Viscount Ashburton. 
As a member of a pure-blood family that is just as prominent in pure-blood society, he was taught about blood purity and its importance. Although he had no disdain for muggles or half-bloods, he took pride in his blood purity and like his father, wanted to preserve it at least in the main line of the family. He married a pure-blood witch himself. 
Matthew attended Hogwarts from 1994-2000 and was sorted into Slytherin House. This was expected, as most of his family is sorted into either Slytherin or Hufflepuff. Matthew was not a very studious student, but was able to get acceptable grades nonetheless. He was more interested in things like Quidditch. He excelled at this sport and was the chaser for the Slytherin quidditch team for many years. He became good friends with Draco Malfoy and Theodore Nott but never took part in Draco's antics.
