My name is Tareq Gamal El-Din Muhamad Othman "Hassan Atallah".
I am sure that my grandfather, Muhamad Othman was a proven descendent of Prophet Muhamad (s.a.w.). The family had the written genealogy until the 1980's, when it was in the hands of Abdal-Menham .... Othman. When he died, his sister was given the information, but she died very soon thereafter and we don't know what happened to the information. ...They lived in in Kafr-Atallah in Al-Sharkiya, the eastern province of the delta of Egypt.
As far as I know, all the occupants of Kafr-Atallah are descendents of Hassan Atallah, who emigrated from the Hejaz to Egypt at the time of Muhamad Ali.
Mr. Sobhi Eid and Mr. Ahmed Wifqi Muhamed Yasin are in charge of an organization of the descendents of the genealogy of Prophet Muhammed (s.a.w.) in the Middle East, called "Nikaabat Al-Ashraf." (Al-Ashraf Union.) Mr. Sobhi's phone number in Cairo is 453-0622. The organization's number is 341-1962.
Messeurs Sobhi and Yasin have published a huge volume of descendents of Prophet Muhamed (s.a.w.). You may be able to order the book from him.
My grandfather, Mohamed Othman, had 2 brothers: Mahmoud and Mustafa. His children are: Gamal El-Din (my father), Ihsan, Sameera, and Tawfiq.
I would be very grateful if you would share with me any information you uncover that would touch on my family or established genealogy.
It's high time that somebody started putting this on the Internet!
