In what's known as the non-canon legends history of Star Wars it is clear that he never married, but there were rumors that he might have fathered children. In non-canon material it is said that Palpatine had a number of concubines and never took a wife in fear that he would produce a legitimate heir.
An Umbaran female, Sly Moore had pale skin and white eyes, and her head was bald. She was always at Palpatine's side—even when he addressed the galaxy from atop his podium in the Senate Chamber—but kept silent in most situations and zealously guarded her master's secrets.
Rey was born on Hyperkarn in 15 ABY during the rise of the New Republic. Her father, Dathan, was a bioengineered Strand-Cast cloned from the genetic template of Darth Sidious, the Sith Lord who ruled the Galactic Empire as Emperor Palpatine.
2019's 'Star Wars: The Rise of Skywalker' revealed Rey to be the granddaughter of Emperor Palpatine.
The birth of Rey
The Emperor's son sired a child of his own, Rey, his daughter who inherited Sidious' power in the Force, unlike himself.
She does not have a baby bump, her hand never goes to her stomach to indicate she's carrying a child, and there wasn't exactly any time for her to have conceived a child with anyone in the course of the film, including Kylo Ren/Ben Solo.
Triclops is Palpatine's illegitimate son, named because of his three eyes. He is sent into solitary exile because the Emperor fears Triclops' potential mastery of the dark side of the Force.
Despite being enemies, Rey and Kylo Ren share a connection called a 'Force dyad' and eventually become romantically involved with one another. Following Palpatine's final defeat and her own resurrection, Rey adopts the name Rey Skywalker to honor her mentors and their family legacy and renounce her lineage.
In addition to rejecting Sidious, Dathan married a woman named Miramir, whom he fell in love with. Together, they conceived a child, their daughter Rey, who was born in 15 ABY. Although he renounced the Sith Eternal and his donor, the Palpatine bloodline would prosper through him, just as Sidious predicted.
As Kylo Ren himself says in The Rise of Skywalker, he and Rey are bonded not just by their familial legacies (Ren as the grandson of Darth Vader and Rey as the granddaughter of Emperor Palpatine) but by their unique connection in the Force.
And answers were finally given by Rey's actor, Daisy Ridley, who admitted that Obi-Wan was originally Rey's father. With the release of Star Wars: The Force Awakens, it was clear the identity of Rey's parents was to be a major part of her story.
In either case, the combined forces of Leia, Luke Skywalker, and his daughter, Rey, would ensure Palpatine's defeat in this alternate Star Wars sequel trilogy.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.
Anakin Skywalker is the son of Shmi Skywalker, born without a father through the Force. He is the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.
The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren: leader of the Knights of Ren, champion of the First Order, and apprentice to Supreme Leader Snoke.
In the context of the story, Snoke is a "genetic strandcast" created by Emperor Palpatine to serve as his proxy in power. Snoke, whom Abrams called "a powerful figure on the dark side of the Force", was introduced as the leader of the First Order and master to the sequel trilogy's primary villain, Kylo Ren.
Even though Finn is once again Force-sensitive, and tries to tell Rey about it throughout the film, the film ends without the story addressing his abilities. While fans were left wondering about Finn's Force status, subsequent Lego films have confirmed it, and Finn is already on the road to becoming a Jedi.
Rey took the name Skywalker to honor their legacy. Palpatine spent all three trilogies trying to turn the Skywalkers to the dark side (he was successful with one of them). You could even go as far as to say that Luke and Leia gave her permission to take the name.
Upbringing. Zayne showed talent in the Force, as many expected, being Rey's son, but the boy was never trained by his mother. Instead, Rey kept her life as a Jedi Master and as a mother separate from her son, reasons being unknown to anyone for close to twenty years.
So does Finn love Rey? No, not like that. The films and comments made from those involved in making the trilogy have made clear that despite seeming to have some romantic tension between them, there is nothing going on between Rey and Finn.
Rey's lightsaber was a yellow-bladed lightsaber that was constructed by the Jedi Rey Skywalker following the First Order-Resistance War.
By the end of The Rise of Skywalker, Rey had become the last known Jedi of the Skywalker Saga. With all that being said, Rey was not left as the last remaining Force-sensitive character.
One could theorize that he bore a child through some sort of space artificial insemination, or something closer to what we've seen in canon Star Wars material. In the canon comic Darth Vader No. 25, it is revealed that Palpatine somehow used the Force to manipulate midichlorions to impregnate Shmi Skywalker.
