Yes, I have met all my blood family. One of these times when I am hauling into P&H there by you we should meet up. Mine has been a fantastic experience.
I have been in contract with my biological father. We haven't physical seen each other but we talk on the phone occasionally and I talk to my two younger brothers and my younger sister on facebook every so often. I also have been in contact with one of my great-aunts. She is my grandma's sister on my biological dad's side.
I happened to find both my dad and my aunt via Ancestry.com while I have been doing my family history research.
My story is ongoing. I've met my sister and three brothers from my birth mothers side. My birth father is a bit of an enigma. Still some sleuthing required there.
