Hey to you Smadar!
I completely agree with Emeraude !In order to help you, you must give the family name of your grandmo including the names of her parents ,and any other information !
If your mom was born in 1946 in Rabat, you can ask for legal birth document which include the names of the parents !
If it's easier for you, you can contact me directly on my email or send me a personal message!
I'm sure that a lot of dafina members will help you !
