I had never heard of this branch of Kuhaylan until Radwan Shabareq told me about a number of Kuhaylat al-Beed (plural of al-Abyad, femine al-Baida) at the stud of Dr. Iskandar Qassis in Aleppo in the 1960s. I don’t know from which Bedouin tribe they came from.
Actually, my mother took these pictures in the 1960s. Hope this link works http://m.facebook.com/j.melkokareem?v=photos&refid=7&m_sess=APJZd-KAo4Iay_&ref=pymk
