‘Abdu’llah (عبد الله slave of Allah) is the name of Prophet Muhammad's father. His full name was in fact Abd Allah ibn Abd al Muttalib (عبدالله بن عبد المطلب). This is proof that the title of "Allah" was familiar to polytheistic Arabs prior to the advent of Islam.
Abdu’llah was the son of Shaiba ibn Hashim (`Abd al-Muttalib). He and Āminah bint Wahb (Muhammad's mother), belonged to the family of the Banū Hāshim, a branch of the powerful Quraysh, the ruling tribe of Mecca, that also guarded the Ka'aba.
