Hi my name is Chanthou. I'm also Cambodian. My family are refugee from the Thailand camps and we are currently living in America. I'm an associate/employee of ancestry.com. I hear ya. I hope things go well with your search. If I hear of anything I will definetly email you. My prayers are sent to you. It must be hard being really young, on your own without any family members.
May God Bless You!
