It doesn't really affect my relationship with my dad; it doesn't change the events of my life. He and I are relatively estranged anyway, so we rarely see each other.
I was thinking I might post something in the DNA queries about this because I have a logic question RE: ethnicity estimates, and I am not sure if I am correct in my assumption. Basically, my father's ethnicity estimate ranges between 0 - 4% Irish ancestry, whereas mine was between 20 - 40%. Now, I know - for sure - that no one on my mother's side of the family is Irish - including the new extended family members I have discovered since.
So, my logical thinking was that there is no way my ethnicity could be greater than his unless my mother or her family were Irish (which they aren't), so my current working assumption is that my biological father (assuming no monumental cock up in the DNA processing) would have to be Irish - or at very least have a lot of Irish ancestry himself.
Which is interesting, as I have matched to lots of previously unknown relations in Ireland, seemingly all from one or two families. I could be way off base, but my suspicion is that my biological father is a member of that family, or very closely related to them.
Unfortunately with my mother being dead, there's not really anyone to interrogate. And I'm turning 40 very shortly, so my dad is in his 60s and my mother would be in her late 50s were she still here, so - depending on the age of mystery man - time might be running rather short in finding out who he is. It might have to be a mystery that goes unsolved.
I'd be really curious to find out who he is. Not so we can have a relationship, but just so I can hear about what happened and try to make sense of it. Right now, I guess I am feeling really sad for my father and my sisters, and quite angry at my mum and mystery man. Though I suppose without them I wouldn't be here, so...
