My favourite female names in Arabic so far: Alia,Latifa,Maryam and Aisha
There is a great song for a girl named Aisha and it really sounds beautiful in my ears
The only problem with Maryam and Latifa is that there already some in the Al Maktoum family and it would be better to chose a name that is not so widly used IMO.
There´s a list with Arabic boy names and their meaning
masculine arabic names
I like the names Hamzah,Faisal and Khaled - as far as I know there are no men with this name in the Al Maktoum family (correct me if I´m wrong!) Hamzah will probably be ignored because of Prince Hamzah from Jordan but I would be happy for a boy named Khaled because of the writer Khaled Hosseini,he writes wonderful books and maybe P.Haya´s son/daughter will follow the tradition and write poems?
