Nice to hear from you.
Is your grandfather Maurice Zwirman, born in Paris around 1930, son of Nusyn Zwirman and Olga Alexandrovitch ?
I am Sylka Zwirman'son, his aunt, which makes him my cousin.
I can still see myself with your granfather smoking our first cigarettes...
If you want to discuss about him and the rest of the family, this is my email :
schenfeigel.michel@hotmail.fr, easier for me to use.
Hope to hear from you soon,
Michel
