Prince Muhammad Bin Ahmed Al-Sudairy descends from a deep-rooted noble tribe, namely Al Al-Sudairy from Al-Dawasir who is a sept   of Al-Azd that immigrated from Ma’rib, Yemen, to other regions of the Arabian Peninsula such as the present-day Wadi Al-Dawasir in Saudi Arabia.

One of Al-Dawasir septs is Al-wadda’ein who are moieties that descend from:  Ghanim bin Naser bin Wada’an bin Salim bin Zayed bin Ziad bin Salim bin Wida’ah bin Amr bin A’amir. One of the branches of the above-mentioned Zayed is Al-Badarin, the descendants of Badran bin Salim. Al-Badarin divide into moieties of which Al-Sadara, as quoted by some references or Al-sadari or Al Al-Sudairy, are the most famous. They are the descendants of: Ahmed bin Salman bin Fouzan bin Turki bin Abdulmohsin bin Muhammad bin Khalid bin Ahmed Bin Farij bin Nasir bin Abdullah bin Mulhim bin Hussain bin Abdulwahab bin A’amir bin Siwayed bin Salman bin Mohsin bin Zaid Bin A’amir Ghalib bin Mohsin BinJawad bin Sadari bin Shakir bin Hajal bin Moshgei bin Hamdan bin A’ayed bin Badr bin Khamis bin A’amir bin Badran bin Salim bin Zayed bin Salim bin Ziad bin Salim bin Wida’ah bin Amr bin A’amir bin Haritha bin Emrei Algais bin Thalaba bin Mar’ib bin Alazd bin Alghoth bin Malik bin Nabit bin Malik bin Zaid bin Kahlan bin Saba bin Yashgob bin Yarob bin Gahtan bin Hood (PBUH). This is the most famous narrative about Al Al-Sudairy’s ancestry. Some references quoted minor differences due to reliance of old historian on verbal narrative. However, most references agree on the above-mentioned ancestral line.

It is noted that the ancestors of Al Al-Sudairy used the name; Zaid, Zayed and Aa’mir. This interpreted why Prince Muhammad bin Ahmed Al-Sudairy titled one of  his poetic folk epics as “Al Zayediah”.   It is also noted that at least two of his ancestors were named “Sidair”, the name which was given to Wadi Al-Fagi in Al-Dawasir after being captured by Sidair bin Aa’mir during the sovereignty of his father on Wadi Al-Dawasir and Al-Ageeg. Later more than one name of Al Al-Sudairy became famous. Examples are:
· Badran bin Salim bin Zayed, to whom Al-Badarin belong.
· Aa’mir bin Ziya who dominated and controlled Wadi Al-Dawasir and its neighbourhood in 780H.
· Sidair bin Aa’mir, whose name was given to Wadi Al-Fagi. Al Sidair branched from him.
· Moshgei, from whom moieties branched in Oman.
· Sulaiman, from whom Al Al-Sudairy, the family of Prince Muhammad bin Ahmed Al-Sudairy descend.

The father of Prince Muhammad was a prominent figure during the era of King Abdulaziz  Al_Saud. He was contemporary with the beginning of establishment of the Third Saudi State. King Abdulziz appointed him as one of his administrative governors, this in addition to his affinity and kinship with King Abdulaziz. Prince Ahmed bin Muhammad bin Ahmed Al-Sudairy, the father of our biographee, is the father of Princess Hissa bint Ahmed Al-Sudairy, the mother of King Fahd and his full brothers. Al-Amira Hissa Bint Ahmed Alsudairy expected all her children and brothers to stay with her if they are in town. She was a great woman called: Umm Fahd , the name of her elder son, King Fahd. We all used to go to her house, the King, my father, my uncles, my aunts and their children. It was a daily uninterrupted big gathering. Umm Fahd was a strong respected personality whose characters of strength mix with her feelings of love and kindness.
Prince Ahmed Al-Sudairy was also the father of Princess Sultana Al-Sudairy, the mother of Prince & poet Abdullah Al-Faisal.
