Character's family

Hey all,

So part of my character is that he was found in the wreckage of a caravan that was destroyed among the bodies of three female changelings. one of navarr, one of urizen and one of highguard but been thinking about trying to find some way of the character actually finding out who his birth family are.

Now none of that really matters except I don’t know how to go about finding a character who could be the extended family or someone who knew who his actual birth parents are. What do people feel would make the most interesting way this could turn out or would advise that I ask to make the plot?
