Double lives, lies and other concealments

It is primarily the story of a man who lived his life with concealments, lies and several double lives. They had tried to bury the story so deep that it could not be immediately found. They promised each other that no one would ever tell anything, especially not to the children. In my family, throughout my upbringing, there were many stories about who was the father of whom. Why that topic came up again and again I have wondered several times. This is a previously secret story that no one other than 3 people and of course relevant authorities knew about. Most families are a bit fucked up when you scratch the surface a little.
