Talia has a daughter on Injustice Universe, her name Athanasia Al-Ghul. Even though for me Athanasia just copy version of Damian before his development with Bruce and Dick (well, she is literally Damian's clone maybe), and I suspected that Taylor created Athanasia because he grow fond of Damian and want to write him on better light, but he still wants a character on his story as bashing punching bag.
On Batman Brave and Bold animation, Selena has a son, interestingly his name is Damian. Even though it turns out that was only Alfred's fanfiction. I am fairly new DC fan, is it common for Alfred to write fanfiction about his master's family life? I also recall he once wrote fanfiction about Dick as Bruce's true son (and has ginger hair). I always see him as noble refined British butler so it's kinda hilarious for me.
