In the heart of the Arabian Peninsula, deeply embedded in its rich history, the Aljeraijeer family stands as one of the noble, urbanized Najdi families. Their lineage traces back to the Al Jledan branch, descending from Harith bin Amr bin Qays Ailan bin Mudar bin Nizar bin Ma’ad bin Adnan bin Ismail bin Ibrahim (peace be upon them), belonging to the Qays Ailan Mudari Adnani tribe, historically known as Jadilah Qays Ailan.
