I, as the name appeared, is one of the descendents that you seems want to find. Datuk Hj Abd Rahman indeed was one of Kamariah Tok A Jabbar's children. He was Penghulu Balai Daik, Lingga. 5-6 of his children and grandchildren married with grandchildren of Sultan A.Karim,Riau, which is one of the small Sultans of Riau that rules Kampar. His daughter, Zaleha, my great great grandmother on my father's side, married Tg Shamsuddin bin Tg A Hamid bin Sultan A Karim. They had 6 children which one of them, tg Maimunah was my great grandmother. Tg A Hamid came to Johor from Kampar/Siak with all the relatives and slaves and stayed at Kuala Sedili, near Johor Lama. When the state capital moved to JB, they all moved to Tanjung Puteri. From there they split and spread all over JB in Gertak Merah and Kg Mohd Amin. Tg A Hamid opened Tiram Duku in Gelang Patah And died and buried there. Most of my families is there till now.
