As I answered a question on StackOverflow, Arabic names can be as long as you want/need… We have this thing called patronymic names.
My full name as I know it is:
.
An English transliteration of that could be “Osama bin Khalifa bin Sultan bin Mohammed bin Sultan bin Sabah bin Saif bin Ahmed (Alassiry) bin Saif bin Mohammed bin Rashid bin Ali bin Sultan bin Braid bin Saad bin Salim bin Amr bin Muadad (Almaadeed) bin Reyes bin Zakher of Bin Mohammed Bin Alawi Bin and Waheeb bin Qassim bin Musa bin Masoud bin Sanee bin Nahshl bin Shaddad bin Zuhair bin Shihab bin Rabia ibn Abi-soud bin Malik bin Hanadhalah bin Malik bin Zeid-manah Bin Tamim (Altamimi)” (The bold names are family/tribe names)
Even for my family names, sometimes people spell them as alasiri, alassiri, alaseeri, alasseeri, al-asiri, al-assiri, al-aseeri, al-asseeri… Almaadeed could be Al-Maadeed, Almaadid, Al-Maadid, Almaadheed, … it’s infinite, and just a way to express the original Arabic name in English. I just like to spell the names the way I spell them here.
