It's an odd situation. He represented the second group of Saxons arriving in southern England and acquired what seems to have been a tiny little realm in Sussex. He then did something unparalleled: he took a fortified position. Non-Romans just didn't do that; they ignored forts and walled towns. If they had to deal with them, they used Roman military engineers, as Attila did. I suspect that this is what Ælle did

His later history is odd too. Even though he became Bretwalda, no later ruler claimed descent from him.
