User blog comment:Merlin919/Is Morgause, Vivienne and Gorlois's daughter/@comment-5102537-20120815202410/@comment-5350801-20120815233227

Why can't Goloris be Morgause's father? Nothing was ever said to the contrary. Nothing was ever stated what Gaius thought or what Morgana and Morgause thought.

The only known facts are this: Morgause was smuggled out of Camelot with Gaius's help (we don't know why she was smuggled, we can only speculate), Morgana and Morgause share the same mother, and Morgana's father was Uther.
