Question: Three people were getting married to each other,  

   Though polygamous they were not.

All men they were in the marriage,  

   Though homosexuality was not in their minds.

They three share two parents,  

   Though they detested the notion of inbreeding. (And this was not, in fact, a consanguineous marriage)

Who are these men?

Hint 1:

Hint 2:

> 
>  45 chromosomes are identical (Not a single difference, even on the atomic level) between the "three men".

Hint 3:

> 
>  Hint 2 does not say that the 46th was different. And two of the "three men" were the same person all along.

Hint 4:

Answer: 
One thought is:

> 
> The holy trinity in Christianity. The father, the son and the holy spirit. All "married" or bonded as one. Nothing in the relationship is sexual. Can be assumed to be male (the holy ghost being somewhat ambiguous). Who the two parents are, I can't be sure.

Another thought, though a bit further out in left field:

> 
> Me, myself and I.
>

> **Edit:**
>   
> As an elaboration, I would say this is regarding someone with multiple personalities. The personalities themselves could be being married, or indeed if the person is being "cured" somehow and the personalities merged into one, this could constitute marriage or bond (whether such a thing is possible, I have no idea). The person is, of course, male.
