Al kisahnya.. Maka setelah Paduka Seri Sultan Abdullah di buang Inggeris kerana skandal pembunuhan Birch, orang-orang besar negeri perak dengan persetujuaan Inggeris melantik Paduka adinda Sultan Abdullah, Raja Musa I menjadi manjadi Tuanku Raja Muda (mangkat 1906) yakni ayahanda kepada Paduka Seri Sultan Abdul Aziz (1938-1948) Paduka Ninda kepada Raja Muda Musa II (1963-1983) Terlalu sedikit kita ketahui tentang Raja Muda Musa I yang juga Paduka Moyang saya. Jika tidak keberatan engku-engku editor sembang kuala ada tambahan info seperti gambar, biodata atau apa-apa sahaja .. mungkin dapat di pamerkan di blog ini untuk rujukan kita bersama..
Teriam kasih.

KuMuz,
Thank you for highlighting about Raja Muda Musa 1. I personally did not aware of the appointment of RM Musa 1 as a result of British intervention until you mentioned it. Really glad to hear about it. At least its also enhances our knowledge. Insyallah, we will try to research more on this area. In the mean time, hope that you could share some photos of your dad. We would love to have it here.
Thanks & regards,

Saya nak tumpang tanya, 11 sons and 10 daughters tu anak betul atau termasuk anak angkat? Arwah nenek saya anak angkat pada Raja Musa Aziz. Nak jugak tahu details lagi
Anak betul.
