I was told at the age of 30 that the person who I believed was my BF wasn't. My full birth certificate states the BF as being unknown and my mum wasn't prepared to talk about it. My nan has since told me the name of my BF and the fact that he had died fairly young. With the aid of technology, ancestry sites and Facebook, I've managed to find a photo of my dead BF and the fact that I have a half sister and three half brothers. I'm not sure if I want to open this can of worms and am not sure how I would be received, given that I have no evidence that he was my BF! But he did die young and it could be something genetic that I should watch out for in me and my two girls. Is this a Pandora's box? Would you open it?
