Here's the thing, I just happened to rewatch The Crystal Cave last night with my boyfriend, finally got him into Merlin, and Uther makes a comment about how he was lonely and how Vivienne was lonely cause Gorlois had been gone fighting on the Northern Plains. Uther claims Vivienne grew lonely. He also states that no one must know "for Arthur's sake." I get the feeling that Morgana was born first at some point.

Furthermore, when Morgause was smuggled out of the kingdom it was when she was a baby. They never gave her age. It is possible Morgause and then Morgana were born and then a year or so down the line Arthur was born.

But even if Morgana was born first, most times the crown was passed down to first born sons. Remember that women were still considered inferior. They only way they would inherit a kingdom was if there was no male heir, and even then they were forced to marry so a king could rule, or the king died. Again, the son would then inherit the throne over his mother, the queen.

One last thing to remember, no matter what the rules of succession are and who is older or younger, this is fantasy, anything can be done with fantasy.
