Credence may well be related to Voldemort, but it would have to be through Voldemort's grandmother. That also means the mystery woman must've had a second child: Merope Gaunt, born in 1907. It's entirely possible that Aberforth could have sired a child with Voldemort's grandmother.
Credence Isn't Voldemort's Dad But He Could Be Snape's Grandpa.
Tom Riddle, Jr (aka Voldemort), was born in December of 1926, just one month after the events of Fantastic Beasts and Where to Find Them. However, after seeing the film, it's clear that Credence is probably not Tom Riddle, and here's why: Magic. Spoilers ahead. Tom Riddle Sr. is a Muggle — a No-Maj if you prefer.
It is explained that Credence is the illegitimate son of Albus's younger brother, Aberforth (Richard Coyle). His real name is Aurelius Dumbledore. Aberforth's wife was murdered, and Aurelius was raised under the name Credance as an orphan.
Is Nagini the mother of Lord Voldemort? No. Merope Gaunt is Voldemort (Tom Riddle Jr's) mother. She died, somehow, and Voldemort ended up in an orphanage.
Nagini is loyal to Voldemort because he can speak with snakes. As a Maledictus, there probably isn't much time after the events in The Crimes of Grindelwald before Nagini falls to her blood curse, becoming a snake forever.
This may have been due to her nature as a Horcrux, which gave her a link to Voldemort like the one Harry possessed. Voldemort was also able to possess Nagini, which he did in December 1995, during the attack on Arthur Weasley.
No. Queenie is not Voldemort's mother. Voldemort's mother is Merope Gaunt, a British Pureblood witch who can trace her ancestry back to Slytherin and the Peverall brothers, specifically, the 2nd brother who had the Resurrection stone.
Credence's costume and hair change are so similar to Severus Snape's that it foreshadows his path in Fantastic Beasts 3 — consequently ruining his ending. Grindelwald abused Credence's need for an identity, telling him whatever he wanted to hear to secure his loyalty in his war against Dumbledore.
Credence may well be related to Voldemort, but it would have to be through Voldemort's grandmother. That also means the mystery woman must've had a second child: Merope Gaunt, born in 1907. It's entirely possible that Aberforth could have sired a child with Voldemort's grandmother.
Nonetheless, despite her initially benevolent nature, Nagini's blood curse eventually turned her into a snake permanently. Though it is unknown if she became evil as a result of that, or was turned evil as a result of Voldemort turning her into a Horcrux. As a snake, Nagini was completely loyal to Lord Voldemort.
In terms of raw power, however, Voldemort is arguably more powerful. Voldemort's followers were no less loyal (and dangerous) than Grindelwald, but Grindelwald's obsession with enlisting Credence Barebones to fight for him shows that he might not have been as powerful as the Dark Lord.
Kendra Dumbledore
Not only did her husband end up being incarcerated in Azkaban, but the whole family had to move from Mould-On-The-Wold, to Godric's Hollow to try and protect her youngest.
"The Secrets of Dumbledore" circumvents the timeline issues by revealing that Credence — or rather, Aurelius — isn't Albus' brother. He's Aberforth's son, which makes him Albus' nephew.
Harry Potter and the Half-Blood Prince
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. Riddle abandoned Merope before their child's birth, soon after which Merope died.
Aurelius Dumbledore (born c. spring 1900), also known as Credence Barebone through adoption, was an English-born American half-blood wizard who lived during the 20th century. He was the son of Aberforth Dumbledore and an unnamed woman. One year after his birth, he unexpectedly was taken to America with his aunt.
They are from different families. Though Queenie might be related to Anthony Goldstein. Yeah, there are some similarities between them like they both were half blood and what u said but they are not related in any way. Also, Queenie was a naturally born legillimen while Snape had acquired that skill.
Severus' lineage on his mother's side was Irish. His maternal grandparents, Muireann Prince and her husband, Roderick, were overjoyed when their daughter had a son. His middle name, Gaeilge for 'Dark Warrior,' was gifted at birth by Roderick when he held him for the first time.
Queenie Goldstein (b. 6 January 1903) was an American half-blood witch and the younger sister of Tina Goldstein. She attended Ilvermorny School of Witchcraft and Wizardry, where she was sorted into Pukwudgie house.
It was such a heavy time, and there was such a reduction of socialization as for being able to, like, see other people, and I was pregnant all throughout the film, and Victoria Yeates [Bunty Broadacre, Newt's assistant] was also pregnant on the film and because we weren't able to do any classes or any kind of in-person ...
Lestrange is the surname of an ancient Dark wizard family. The most notorious Lestrange from the "Harry Potter" series was Bellatrix — the cousin of Sirius Black and Lord Voldemort's most devoted follower.
Quentin Kowalski may be a descendant of Jacob and Queenie Goldstein, though this would breach Rappaport's Law. Queenie and Jacob would need to have left the United States of America to marry as to protect Queenie from prosecution.
When Harry and Hermione are on the first floor of Bathilda's house, Nagini (inside the corpse of Bathilda) tells Harry to "Come!" from the next room in Parseltongue. In reaction, Hermione jumps and clutches Harry's arm, and the two of them obey the command.
Nagini, Voldemort's snake, then eats Professor Burbage's dead body. A story about her "resignation" from Hogwarts appears in the Prophet, but members of the Order of the Phoenix discount it, as they are unable to locate her anywhere after that. Burbage is later replaced as Muggle Studies teacher by Alecto Carrow.
It wasn't just inanimate objects that could become Horcruxes. Lord Voldemort's beloved snake companion, Nagini, was also transformed into one, and Dumbledore seemed to know it, ominously predicting that a day would come where Voldemort would 'fear for his snake'.
