Just to make it clear, I'm a MALAY. Proud to be one :) but of course, there are the mix thingy.
Chinese + Pakistanese + Rawa + Minangkabau
On my mother side : my grandma is Pakistanese/Arab. We do have the Sheikh/Syed/Sharifah, but we dropped the name. I have relatives in Singapore but I don't know about them much ^^ my grandpa is Malay + Chinese. My great grandfather is Chinese. I heard that he used to work as an actor in the traditional chinese opera before he converted into Muslim
On my father side: My grandma is Malay + Rawa. My grandpa is Malay + Minangkabau. Purely Rawa and Minangkabau :)
