As above, DNA has come up before, But I recently found out through a DNA match that I had had a half brother, he would have been 10yrs older than I, unfortunately I did not get to know him before he passed away.
I recieved an email from a fellow that thought all his life he had a certain surname, but found out through his DNA search his father was my half brother.

 

We live in odd times. A lot of people went to their graves thinking they took their secrets with them. Now 23andMe is spilling the beans. I know of two local friends that lived their lives, until now, incorrect about who their actual fathers were. It's made for some interesting and awkward conversations, but overall I'd say it's been very satisfying to these people to learn the truth.

Its something we may never know, but from the info I have so far, it could have been that my father never knew of his offspring!?
