Hey anyone knows if Merlin ever had children according to Arthurian literature......according to Arthurian history Arthur was illegitimate son of Uther....

I don't hear nothing about Merlin had children. i guess not.

Merlin's traditional biography casts him as a cambion; born of a mortal woman, sired by an incubus, the non-human wellspring from whom he inherits his supernatural powers and abilities. Merlin matures to an ascendant sagehood and engineers the birth of Arthur through magic and intrigue. Later authors have Merlin serve as the king's advisor until he is bewitched and imprisoned by the Lady of the Lake. No mention if Merlin ever having children of his own.
