They are looking for bloodline.

Many moons ago back in probably early 80s the Sheriff office in Yates County (yeah its Finger Lakes) did a “service “ to all our parents and had us finger printed and blood typed. I dont remember it but I still have the paper. It says I am O+. Not sure as Ive never donated blood nor had a surgery to be cross type and matched. Kinda thinking I dont want to pursue it either. 🧐

Another puzzling question I have is this.. I have “googled” this and because I dont trust “science” … My parents and my sister are all brown hair, brown eyed and right handed and all have A+ blood. Im blonde, blue eyed, left handed and supposedly O+.. how is this possible? Googling says any blood type can produce any blood type.. something just doesn’t set well with me and that answer.
