This is Toan, x.Dau. I am a catholic priest!
My family name is DAU. We are in Vietnam.
But we also have many our DAU families are living in US.
I do not know Esther Dau is our big family or not.
But if the family name is Dau, i believe that he/she belongs to our big family.
Some words to you, I hope we will continue to find out the real family of Esther Dau.
May God give you peace and happiness!
Fe. Toan, X.Dau
