Thanks to Facebook...

... my brother was able to find my step-sister on my dad's side, then my little half-sister! Obviously we found much of my dad's family on FB after that, and eventually, we found my dad. (OMG. It's only taken us like 10 years!) We met up with him a few times to kind of catch up on things. G didn't seem to care that it may have been a little awkward for my dad... oh, and I'm pretty sure my dad has no idea I took his picture!
