In the post-Flashpoint Earth 2 continuity, Helena Wayne was the daughter of Batman and Catwoman (Bruce Wayne and Selina Kyle Wayne). She was also the only Robin to her father's Batman identity and a more ruthless character than previously seen.
Helena Wayne is the original incarnation of The Huntress, originating from the original golden age Batman continuity of Earth 2. Helena was the biological daughter of Batman and Catwoman, raised to be a lawyer-by-day/vigilante-by-night and eventually became her father's successor.
In Batman and Son, Morrison re-introduced the son of Bruce Wayne and Talia Al Ghul, Damian Wayne, to continuity, who had been raised by his mother in the League of Assassins.

Who is Batman's true son?
Among the big announcements from James Gunn about the future of the DCU was news of a new Batman in a film called The Brave and the Bold. This movie would have our first big-screen Robin in 25 years. But that Robin won't be Dick Grayson, but Damian Wayne, Bruce's biological son.
In the post-Flashpoint Earth 2 continuity, Helena Wayne was the daughter of Batman and Catwoman (Bruce Wayne and Selina Kyle Wayne). She was also the only Robin to her father's Batman identity and a more ruthless character than previously seen.
Kull was the daughter of the superheroes Batman and Wonder Woman from a world of the Dark Multiverse. Her mother trained her in the art of Amazonian combat and she was trained by her father as well.
Unfortunately, having a living mother and father didn't last very long for him—at least, not in their original continuity. Following the untimely death of Tim's biological family, Bruce eventually did legally adopt him, but it took a while for that to actually come to pass.
In the process, he begins the training that shapes his destiny as a feared vigilante, known as Batman. In Pennyworth, Bruce is revealed to have had an older sister, Samantha, who disappeared long before he was born.
Their history on the Earth-Two continuity developed to the point where Catwoman reformed and Batman admitted his love for her, formally marrying shortly after and having a daughter, Helena Wayne, who later became the Huntress.
The original Earth-2 Batman ended up marrying his Catwoman and fathering Helena Wayne/Huntress. However, it took a while for the modern Bruce Wayne to accept his feelings for Selina, and the two officially revealed their identities in 2002's Batman: Hush before later getting engaged in the Rebirth era.
In John Byrne's Elseworlds comic book series Superman & Batman: Generations, Superman and Lois have two children, Joel and Kara Kent. When Lois was pregnant with her son, Joel, Lex Luthor and the Joker exposed her to Gold Kryptonite radiation, causing Joel to be born without any of his father's powers.
One of the things that sets Batman apart from other DC heroes is that he is motivated by intense trauma. While all superheroes have some sort of traumatic past, the death of Batman's parents is such a foundational part of his character that it's hard to imagine him without it.
So if Superman and Wonder Woman have a child, and she / he inherits Wonder Woman's strength and Superman's ability to absorb sunlight, that child would have 1000X of strength without sun and in the presence of sunlight it would have 1000000X.
Talia was briefly married to Batman and is also the mother of Damian Wayne, Batman's biological son and the fifth Robin. Created by Denny O'Neil, Talia first made her debut in Detective Comics #411 (May 1971) with original outfits being penciled by Bob Brown and later Neal Adams.
As Diana Prince, she works in the U.S. War Department as an assistant to intelligence officer Steve Trevor. Decades later she and Trevor marry and have a daughter, Lyta (also known as Fury).
She became a thief for survival and eventually turned into a vigilante, partnering with the vigilante Batman. The two developed a romance and she unexpectedly became pregnant, which left her unhappy as she thought she would have to settle down.
The ceremony was cut short, however, when Selina's friend Holly Robinson convinced her not to go through with the marriage. Selina's reasoning for calling it off was that she didn't want Bruce to have to stop being the Dark Knight for her and thus left him standing at the altar.
Later, Arthur goes to Arkham State Hospital and steals his mother's records, and finds out that he was in fact adopted, and that Thomas Wayne is not his father and that Penny is not his true mother.
Terry is the vigilante known as Batman in the future, having taken over the mantle after the aging Bruce Wayne retired. He eventually learns that he is a biological son of Wayne, created through covert genetic engineering by Project Cadmus. However, neither knew of their relationship at first.
Jean-Paul Valley is notable for being the first character to take on the Batman mantle after Bruce Wayne. He was a major supporting character during the '90s, particularly in the iconic Knightfall story arc.
