A friend of my mother-in-law did the same and found she had a half-brother.

Shouldn't that be in breaking news?

Your mother-in-law probably likewise has "secret" half-sibs.

People of that generation hushed up such things.

I doubt she does. Her family was and still is pretty tight.

Now my father in law, it’s almost certain. His father was a derelict who went out for bread one day and forgot to come home. 40 years later they found out he was still alive.
