If you are in the U.S.A. and you know what State and County his children were born in, you can go to that County's Courthouse and look up the birth records.





Just look for your father's name as the father on the birth records.





I have looked up many children like this, for my Family Tree.What is the best site for finding relatives of a deceased parent?
That depends on what country and state/shire/province you live in, how much you are willing to pay, if the women in question are still minors and if they know who their father is.





You could try a post on the Ancestry and GenForum boards for his surname, or one of the parent/child reunion boards normally used by adopted children and bio parents.





Pictures are basiclly worthless until someone contacts you, unless you have a friend at the FBI or CIA.
