Rowling uses several chapters as exposition to establish Voldemort's backstory. In a series of flashbacks, using the pensieve as a plot device, she reveals that Voldemort was the son of the witch Merope Gaunt and a Muggle called Tom Riddle.
Marvolo Gaunt (fl. 1925) was a pure-blood wizard of the House of Gaunt and descendant of Salazar Slytherin. He was the father of Merope Riddle (née Gaunt) and Morfin Gaunt, the maternal grandfather of Tom Marvolo Riddle (later known as Lord Voldemort) through his daughter Merope, and the great-grandfather of Delphini.
It is known that Harry is a descendant of Ignotus Peverell (The brother that received the Invisibility Cloak), and Voldemort is descended from Cadmus Peverell (The brother that received the Resurrection Stone). So it's not too far-fetched to think that Snape could also be a descendant of one of the brothers.
Tom Marvolo Riddle (December 31, 1926 – May 2, 1998), later known as Lord Voldemort, was a half-blood wizard and considered to be the most powerful Dark Wizard of all time. He was the son of wealthy Muggle Tom Riddle Sr., and witch Merope Gaunt, who died shortly after childbirth.

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").
Delphini was born in secret at Malfoy Manor in early March 1998 as the result of a liaison between Bellatrix Lestrange and Lord Voldemort. On 2 May 1998, both of her biological parents were killed in the Battle of Hogwarts.
In the tale, the older brother sought power and to conquer death, and was killed by another wizard while he slept. Voldemort also sought to conquer death, thus why he created various horcruxes. Snape is the second brother, Cadmus Peverell, who crafted the Resurrection Stone.
Harry, as heir of Gryffindor, possessed the love of this Muggle-born woman in his very blood and was the perfect champion to stand up against the heir of Slytherin.
Rolf followed his grandfather's footsteps and became a magizoologist himself, eventually falling in love with Luna. This makes Luna Lovegood the great-daughter-in-law of both Newt and Tina Scamander, further cementing another prestige family lineage in the Harry Potter canon.

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.
An interesting fact of note is that despite the ideals that pure-bloods are inherently more powerful wizards, some of the most powerful or particularly adept wizards and witches in the series are in fact either half-blood (such as Lord Voldemort, Albus Dumbledore, Minerva McGonagall, Severus Snape and Harry Potter) or ...
Also, James Potter was a pure-blood. One possible theory indicates that the author of the Directory considered the Potters and other "pure-blood" families (such as the Princes, the Crabbes, the Goyles, the Moodys, and the Browns) to have some amount of Muggle ancestry.
