I never heard about that marriage
Akshayakumara (Akshakumara) was the youngest son of Ravana and the brother of Indrajit. In the Ramayana, When Hanuman started destroying the Ashoka Vatika after talking to Sita, Ravana sent him at the head of a Rakshasa army to take care of it. It is mentioned in the Ramayana that when the news of Hanuman's destruction of Ashoka Vatika reached Ravana's Court, Ravana looked at his young son, Akshayakumara. A warrior of just sixteen, he took the gaze of his father as his command and left for battle in his flying chariot.
He fought valiantly with Hanuman, aiming various weapons at him. Though highly impressed by the young prince's valor and skills, finally Hanuman had to kill him.
Ravana was filled with grief at this news.
