Harry James Potter holds half-blood status in Rowling's imagined wizarding world because his mother is Muggle-born and his father is pure-blood. There are three main blood statuses; pure-blood, half-blood, and Muggle-born, which are all methods of determining a witch or wizard's magical lineage.
Potter is a common Muggle surname. Harry's family didn't make the list, according to J.K. Rowling, because 'the anonymous compiler of that supposedly definitive list of pure-bloods suspected that they had sprung from what he considered to be tainted blood'.
"Pure-blood" is the term applied to wizards and witches who have no Muggle blood, Muggle-borns, or half-bloods at all in their family trees. They are the rarest of the three blood statuses, with J.K. Rowling stating that ten per cent of the wizarding community is made up of pure-bloods.

Voldemort's past, as revealed by the books, is shrouded in mystery and guesswork. In fact, at the beginning of the series, barely anyone but Dumbledore and Hagrid knew that Voldemort was the charming, successful Tom Marvolo Riddle.
Severus Snape was only 32 years old when Harry went to Hogwarts for the first time. And 38 years old when he died.
And, naturally, J.K. Rowling herself is a Gryffindor.

Later in the year, McGonagall duelled with Death Eater Alecto Carrow during the Battle in the Astronomy Tower and later learned of Snape's murder of Dumbledore.
