Im not saying this in a mean way, but you really had a fucked up life, dont you Poly?Wish you best of luck.
On the topic at hand, I never been on such a scenario, nor never will, given my parents age.And honestly, unless you actively seek them out or you have a family issue, like heritage, in which bring you guys "together", you will likely never meet them.But I am of the opinion that family is made of people that you care about, not that you are bound by blood, so in my view that wouldnt be an issue(of you never meeting them).
