Re: Warded to Roger/Dean
I grew up without my birth father too, although I had a stepdad from when I was fairly small, I knew almost nothing about my father for years. I only looked for him after the war because Mum hadn't liked to talk about him.
I think, given the circumstances, I'd say go for it. Finding out about him might not turn out well or how you think, but if you don't like him you don't have to contact him again.
My story had an okay ending. Not something I talk about much, but my father died not long after I was born. Death Eaters. But it doesn't look like he didn't want me.
