need to find my father for my boys so they have family

How about the father/fathers of the boys families?

Even if the man or men are unwilling to be father/fathers the rest of his/their family/families might not feel the same and might be eager to enter the boys lives.

Good luck in any case.

Are you expressing the angst to get some feedback or are you asking how to go about doing this?

There's another topic where this poster has replied. Apparently there is her biological father who came into her life and has disappeared again.

There are services who will find people for a fee and usually it is not an exhorbitant fee since that doesn't require a lot of legwork these days.

When my own biological father 'disappeared' for eleven years I didn't much want to find him, but even though he did not deserve to be in our lives, I was curious as where he was. I had heard rumors that he was in the Denver area and, when hubby was sent to a training school in Denver, I asked him to see if he could locate him. The telephone operator confirmed that his telephone number was unlisted so hubby explained the situation and asked the operator to see if he would be willing to call hubby.

My father's wife (not my mother) called to advised that my father had died 30 days before. She didn't bother to notify anyone in the family even though it turned out she knew where all of us were. She left town before my dad's very angry sisters could get at her and has not been heard from since.
