Thank you all for your responses. To answer the questions:
There is no one we can ask - obviously his parents took great pains to hide the fact that his father was not his biological father. Family members were the ones who informed him that he was already 4 when his parents married, but that's all they know. When we started digging, obviously we found this to be the truth. Since he's found out, his mother is no longer talking to him. So there are no answers to be had there.
What we are looking for is legal evidence that this man is his father. So my question is, what would the process have been in this time period (1968-1975) for the birth record to be changed in Indiana. I am in california, and I know that here, you cannot just remove a biological father from the birth certificate. It's has to be done by court order. Knowing what the process was will help us ask the right questions at the court house.
His purpose is to have legal proof that this is his father, so that he has legal standing to get records such as the birth and death certificate, army records, etc. to find out the person his father was, and whether the man has any living siblings that we can locate.
Thanks again.
