Seeking for Grandfather

Hi,

First of all, thank you for this site. I have been trying to find ways of seeking for my grandfather. This site certainly give me hope.

My mother is certainly a child of the Vietnam War. She was born in 1961 to an American father. We have no name, no address, ONLY a picture of my grandfather.

Please advise me on how I can go about finding my grandfather. I need to do this for my mother. There is a chapter in her life that contains only questions and no answer. I want to be able to find the answer for her.

Sincerely,

Nina Ho
