Duela Dent first appeared as the Joker's Daughter in the Batman Family series of comic books. She gained the attention of Robin (Dick Grayson), as she later claimed to be the daughter of the Catwoman, the Scarecrow, the Riddler and the Penguin.
Ultimately it was revealed that Duela is the daughter of the The Jokester (Earth-3) and Three-Face (Evelyn Dent) , the Joker's heroic counterpart and archenemy of Owlman (Thomas Wayne, Jr.) This means she is Joker's daughter, just not the mainstream one. She is also the step daughter of the Earth-3 Riddler.
That mystery is quickly solved as The Joker gives "birth" by puking up brown goo in the next few panels of the comic. The sludge then forms into a young boy who looks very much like his father. One panel shows both The Joker and the newborn staring at each other, thinking "he's so handsome" in a shared thought bubble.
With false implanted memories in his head, Dick Grayson becomes the Son of Joker, and it looks as though he just got a pretty gross inheritance in Red Hood and the Outlaws #48.
One of the mysteries in director Todd Phillips' Joker is whether Arthur Fleck really is the son of Thomas Wayne as his mother Penny Fleck claimed. Both Wayne himself and Alfred Pennyworth said it was untrue and that Penny was delusional, hence her eventual stay in Arkham Asylum.
DC has made it common not to give The Joker any solid backstory or family, but they still managed to accidentally give him a son. Due to DC canceling a comic just a bit too early, they unintentionally left Joker with a son in the form of Lonnie Machin, also known as Anarky.

Batman carries a well-deserved reputation for burning through sidekicks faster than Batmobile tires, and while Dick Grayson remains the most famous Robin, numerous others have held that title. Following Grayson, Jason Todd and Tim Drake in mainline DC continuity is Damian Wayne, Batman's biological son.
To make this happen, the most famous clown in comics persuades the wizard Zatanna, however, she wants nothing to do with the Joker and she casts a spell but it backfires and he is the one that becomes pregnant.
In "Knocked Upside Down" from The Joker: The Man Who Stopped Laughing #4 (by Matthew Rosenberg, Francesco Francavilla, Tom Napolitano), the Joker is cursed by Zatanna after he makes a pass at her and ends up becoming pregnant with his own child.
Zatanna casts a backwards curse on him: “On eno esle lliw reve evah ruoy ybab!” (“No one else will ever have your baby!”). This results in the Joker waking up pregnant.
Following her introduction to the comics in 1999, Harley Quinn was depicted as the sidekick and lover of the Joker as well as the criminal associate and best friend of Poison Ivy.
The feminine of Clown or Joker in English is … Clown or Joker since neither are gendered words. There's no such title as 'Clowness' or 'Clownette' nor 'Jokeress' or 'Jokerette'. A woman who is a clown is a clown, just as a man who is a clown is. The same with 'Joker' which is simply someone who tells jokes.
Penny Fleck was the adoptive mother of Arthur Fleck, a mentally unstable failed comedian who would later call himself the Joker. Much like her son, Penny suffered from an unspecified mental illness.
Joker Killed Jason Todd to Destroy His Own Conscience, DC Implies - IMDb. Jason Todd's brutal murder at the hands of The Joker is one of the darkest moments in Batman's mythos, but The Clown Prince of Crime may have killed the second Robin to destroy what is left of his conscience.
Jason Todd is the second Robin after Dick Grayson and the sixth Red Hood, who was subject to the first Red Hood, The Joker's torture. He was killed by Joker, but was later revived by the League of Assassins, becoming an enemy of his former mentor; Batman, all in a scheme to kill the Joker.
Batman and Joker definitely aren't brothers in the comics. While the Joker movie plays very deeply with this idea, it still maintains the same stance. In the books, Joker's origin story has been a mystery. Readers have come across multiple different ones over the years.
As mentioned previously, Joker's surface-level position is that Penny Fleck was delusional, imagined the affair with Thomas Wayne, and what's more, actually wasn't even Arthur's birth mother.
While it's not a perspective fans are used to seeing, it's a fascinating look at a Batman who is more vigilante than superhero, and whose hatred for Joker isn't rooted in awestruck disbelief at his depravity, but frustration at having to lose another night of his crusade to a villainous clown.
According to Penny, Arthur was born of an affair she had with Thomas when she worked for him. She said in a flashback that Thomas' wealth, power, and influence helped to produce the claim and paperwork that Arthur was adopted.
