I wish you a Happy New Year too :)

I am sorry but I did another search and I still didn't come up with something that would be a straight match, the search area is still too broad.

Try to find out the names of the sisters and perhaps find the death or marriage certificate in order to find out more details about him.

Let me know when you've got more and I'll give it another try. Once you nail down who it is and you've got the his details in Sweden it is pretty easy to track down both living relatives as well as further down the line.

Just ping me another note here when you have more information

Good luck
Anna
