My Dad is 96, far too old to cope with another op - he had it fixed once but either it's another finger that's doing it or something went wrong. There are no Scandinavian names in the family tree and it's only this condition that points to that ancestry.
I've always had very pale skin too, from my mother's Scottish side, only teamed with blue-gray eyes. My father is half Romany and tans easily. There's apparently some Irish in there too.
Interestingly, I only found out about the Romany background ten years ago - it was something of a shameful family secret (though weirdly a fortune teller told me I had Romany ancestry when I was only 17). Partly because my grandmother was supposed to have second sight which my father claims was passed on to him. This is in a Christian fundamentalist family, so it's easy to see why this was hushed up. Apparently they could both see ghosts and were clairvoyant, though they tried to suppress their 'gifts', according to their religious beliefs. I've long considered my father borderline psychotic and from descriptions of his 'clairvoyant' experiences that turned out to be true it sounds no more than cold reading and confirmation bias.
Apparently there was a Spey-wife (fortune teller) in the Scots side of the family at some point too.
I'm really envious of all these people with Native American heritage - that always seemed a really cool thing to have.
