My name is Adriana Savin, I live in Sweden.
My father, Lucien Savin, was born 1923 in Bucharest, Romania.
His parents was Levy Segal and Mina Schmidt. Levy´s father was Nathan Segal.
Can this possibly be the same Nathan Segal you´re writing about?
I´ll look up where and when my grandfather Levy was born...
All the best, Adriana Savin
