I am B +. My family are Scots as far back as anyone can trace them
Oh no! ; not Scottish ancestors! ? At least I'm now living amongst Asians!
Thank you all for your comments. I've more than a passing interest in this topic; our 2 boys were born in 1957 and 1959 respectively when knowledge of incompatible blood groups was only just emerging. Vera was O- and me B+, but we knew nothing of what lay ahead. Neil No1 was OK apart from a severe allergy to dairy (cow's milk) and peanuts, but that's another story. Ian No2 almost died in the womb, motionless at 8 months and was closely monitored to a natural birth. He was immediately rushed away, strapped to a little cross and transfused, a very small amount of "bad" blood removed then the same amount of donor blood returned. Scary times!
Neil being No1 was clear of antibodies, but Ian copped the lot which would continue to remain with Vera and so we were advised that any No3 would have no chance of survival; so, no No3.
It's marvellous what progress and understanding of this subject has occurred since; e.g. transfusions actually in the womb.
Both "boys" are now strapping 6-footers, 62 and 60y.o., but not best pleased at being eligible for the "Senior's Menu"!
