From your link: Al-Husseini was the scion of a family of Jerusalemite notables, who trace their origins to the grandson of Muhammad.
Hmm? Didn't Muhammad hail from the Arabian Peninsula?
My suspicion that Mr Haj Amin Husseini was not indigenous to the Holy Land was confirmed when I linked to a link from your link:
The Husayni (Husseini) clan claim descent from Husayn ibn Ali, the grandson of Mohammad, the founder of Islam; Husayn hailed from Medina, which is in the Arabian Peninsula." (
al-Husayni - Wikipedia the free encyclopedia)
I am now in the process of investigating other notable "Palestinian" families to see whether they're indigenous to the Holy Land or, like the Husseinis, are squatters that hail from the Arabian Peninsula.
Thanks for the initiative, poster.
