A known company belonging to the Malfoy family was the Malfoy Apothecary, which sourced Superior Red wine, a name perhaps hinting at their characteristic blood purity.
The Malfoy family, known for despising Muggles and Muggle-borns, actually gained property and wealth through interactions with Muggle royals. Draco Malfoy, influenced by his prejudiced father, eventually grows out of his family's pure-blood mania, which was ingrained in the Malfoys' ethos.
Lucius lived a rather good life with his family. Independently wealthy and therefore without any need to work, he was more than content with a settled life, preoccupying himself with upholding his influence in the Ministry of Magic and maintaining a collection of Dark artefacts harking back to family history.
From the Cursed Child, we know that Draco father Lucius wanted him to be in the Ministry, but he wanted to play Quidditch. In an alternate reality, he was Head of Magical Law Enforcement, Harry's job in the real world. But Draco is living off the Malfoy family riches, without any need to work.
They had about 321,000,000 galleons, about 2.2 billion dollars, and 1.6 billion pounds. They were probably some of the richest families. Overall, the Malfoys seem to be the richest and most wealthy, however, there must have been other families out there that had a plentiful amount of money as well.
As an adult Luna became a famous Magizoologist, a wizarding naturalist. She discovered and classified many species that had never been encountered before. She was also shown to be very skilled at handling various magical creatures, such as Thestrals, showing her proficiency in Magizoology.
Rowling elaborated on Ginny's future after the release of the book, saying that after leaving Hogwarts, she joined the Holyhead Harpies and, after spending a few years as a celebrated player, retired to become the senior Quidditch correspondent at the Daily Prophet, and to start a family with Harry.
She married Rodolphus Lestrange after leaving Hogwarts "because it was expected of her" to marry a pure-blood. However, Rowling stated in an interview that Bellatrix truly loved Voldemort.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Originally Answered: Were all Death Eaters Slytherin? Yes, with only two notable exceptions: Quirrel was a Ravenclaw, and that traitor Wormtail was a Gryffindor. And of course there were also Death Eaters in other schools, such as Durmstrang's Karkaroff.
The pure-blood wizards and witches featured in the Harry Potter books are almost all supremacists, while there are some of them who do not advocate ancestral superiority; the Potters, Weasleys, and Longbottoms are old pure-blood families, but no known members of these families are sympathetic to supremacist aims.
As the eldest of three sisters, Bellatrix was first in line to inherit their parents' possessions when they died. She also would have merged her assets with those of her husband, Rodolphus Lestrange (another bloodline featured in the Sacred Twenty-Eight). The most convincing proof lies in Bellatrix's vault.
Harry Potter had a few love interests during his time at Hogwarts. Though he eventually settled down with Ginny Weasley, he also had a thing for Cho Chang in his earlier school years. Then, of course, there's his secret love for Draco Malfoy…
Sometime after Pansy and Draco had finished their education, their friendship ended. Draco's changed views on pure-blood supremacy, caused by the events during his last year of school, may have contributed to this.
Rowling revealed more information about Neville when she stated that he married Hannah Abbott, a Hufflepuff classmate, who became the landlady of the Leaky Cauldron. The couple live over the pub, a fact that Rowling thought people would find "particularly cool".
Luna married fellow naturalist Rolf Scamander, grandson of Fantastic Beasts and Where to Find Them author Newt Scamander, considerably later in life than Harry, Ron, Hermione, and Ginny, who all married and started families in their early-to-mid twenties.
Under the influence of her father, Dolores grew up despising her mother and brother for their lack of magical abilities. She was sorted into Slytherin House at Hogwarts School of Witchcraft and Wizardry and hated her time at the school due to never being given any positions of power.
The Weasleys were known in the wizarding world for being of lower economic status, something the Malfoys loved to remind them of. On the other hand, Harry had inherited a small fortune from his father, who had been the heir to the wealthy Potter family.
Harry is the richest student at Hogwarts by default. He inherited his parents money (and later the Black fortune) - and it was his and his alone. If he wanted to empty his vault and spend it all on sweets, and Quidditch brooms - he could. There was nobody to stop him.
