There are a few Ilha residents whose features suggest non Bantu African ('black' African) genetics. They sometimes show Arabic or Portuguese/European genes. The man in charge of the barrier to the bridge, the lady who owns O Paladar restaurant, the tailor's chum from earlier in the blog, the lady running the tiny convenience store in the colonnade are examples, as well as this shopkeeper in the hardware shop in stone town south of the main mosque, where I bought a grill for our charcoal barbecue.
