In canon no Obi-Wan doesn't have kids. However, there is this theory where he and Satine had a child together but she hide it from him, knowing how it could ruin his jedi career. This child would be Satine's “nephew” Korkie Kryze…
The love story of Obi-Wan and Satine
So far, in canon, it hasn't been revealed if Obi-Wan ever fathered a child, but the possibility hasn't been definitively refuted either.
Korkie Kryze, a Mandalorian human male, was a cadet of the Royal Academy of Government on the planet Mandalore during the Clone Wars.
Leia Organa is Obi-Wan Kenobi's daughter.

But their romantic connection was strong enough that, years later, Obi-Wan actually revealed that if Satine would have asked him to stay with her, he would have left the Jedi Order. Satine eventually confessed her love to Obi-Wan on Mandalore after Maul used her as bait to draw the Jedi to the planet to save her.

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.
The daughter of Duke Adonai Kryze, Satine was a member of Clan Kryze, a clan aligned with the Kalevala-based House Kryze, at one point considered the Mandalorian royal family. Satine also had a sister, Bo-Katan, who she was close with when she was younger.
In the original Star Wars: Episode VI – Return of the Jedi screenplay, Obi-Wan did have a brother, and it was none other than Owen Lars (Joel Edgerton)—Luke Skywalker's step-uncle and Anakin's step-brother.
Why does Obi-Wan Kenobi age like that? Because he's not real, and is a fictional character played by different people. You see, Obi-Wan Kenobi is played by Alec Guinness in the original trilogy. Guinness was 62 when he filmed A New Hope, and he died in 2000.
Obi-Wan is Anakin's daddy, not his father.
Yes, he fell to the dark side and became Darth Vader, but that wasn't entirely his fault (the Jedi Council needed to rethink their take on human emotions). Many thought Anakin was “The Chosen One” prophesied to bring balance to the Force.
Although Obi-Wan and Satine never married or became an official couple, there was an undeniable romantic connection between the two. In Star Wars: The Clone Wars, Obi-Wan told Satine he would have left the Jedi Order if she had asked him to stay. Satine also told Obi-Wan that she had always loved him.
In the timeline of the series, Vader was last seen siding with Emperor Palpatine, betraying his Jedi peers and losing the love of his life, Padme Amidala. Unbeknownst to him, Vader's two children - Luke Skywalker and Leia Organa - remain alive and in hiding.
The Inverse analysis — The new revelation that Leia was buddies with Obi-Wan when she was a kid isn't just some cool canon twist, it also adds a tragic layer to everything that happens in A New Hope. Leia doesn't get to reunite with Obi-Wan, and instead, just before escaping with Han and Luke, she sees his murder.

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.
That's ok, but a little disappointing. Since The Last Jedi outright says Rey's parent were not important (from a certain point of view), and Luke shows no indication that he knows who Rey is, or even cares, it'd be really hard to justify that original idea.
Despite the ban and the associated dangers, many Jedi, including Kento Marek, Ranik Solusar, Nejaa Halcyon, Revan and Anakin Skywalker, wed, either in secrecy or with the knowledge and disapproval of the Jedi Council.
As the conflict raged on, she learned that its politics were not as black and white as she once thought and eventually entered into a relationship (and marriage) with Lux Bonteri, son of former Confederate senator Mina Bonteri.
In the Jedi Order, emotional attachment and possession were forbidden because it was believed they could lead to jealousy and fear of loss, and ultimately the dark side of the Force; for that reason, Jedi were not allowed to marry.
As time goes by, Obi grew more attached to Zen and later even admitted that he 'likes' Zen when he was confronted by Zen.
Obi confesses his feelings about Shirayuki to Zen not because he wants to declare himself a rival, but because he also loves Zen.
