Searches: Wiki'd and googled with "Demi-god" "demigod" and both of these with "Birth" attached and mostly ended up with Jesus links (which is not what I need).
I am looking for stories of demi-gods with strange or miraculous births and/or heroic/ incredible deeds shortly after their births. I'd prefer ones not from the Greek or Norse pantheons and I have used Heracles and the Norse god Vali and I want some variety. Any and all suggestions are welcome, though, if you think the demi-god fits the criteria.
Thank you in advance for all your suggestions. :D
EDIT: Thank you for all the interesting mythology and god information. I am, however, only looking for stuff that relates to HALF-GODs' births, and not full blooded gods.
