Ok so this is a necro but this may be found by someone in the future so maybe it will help. The writers tried to stick with the actual legends about Arthur. In the legends Morgana is at least 2 years older than him, once when Uther was away at war he (regrettably) cheated on his wife. It ranges 2-5 years. Some versions of the legends even have Morgana and morgause as Ygraines children from a previous marriage but that's not as popular. Either way in all versions of the legend Morgana is always the eldest.
