I also have the same problem. I need to find the birth certificate/any document of my grandfather. He was born in Tripoli in January 29th, 1889. He then left to Brazil after getting married in Lebanon to my grandmother Martha Felippe. His name was Moyses Abrahao, but in Brazil they changed his last name from Ibrahim to "Abrahao".I would like to apply for the Lebanese citizenship so I really need these documents: birth certificate or marriage certificate. Please, I hope that somebody would be able to help me because I don't even know where to start from.
