[KS] Hwan-Ung - Illegitimate?

[Bert Edens]

Greetings, all...
	I know there are several references to Hwan-Un being the illegitimate son 
of Hwan-In, but are there any references as to the story behind it? Or do 
they just say that he is, and leave it at that? Especially considering the 
"clan / totem origin" possibilities of the Dan-Gun myth, it makes me wonder 
about this...
	Thank you in advance for everyone's time.
