She's intriguing. Her surname is Lewis, but that might be from marriage, or just an old colonial name; or she may have chosen it. In Tanzania, an educated person would probably speak English on top of Swahili and perhaps another language. Mona's looks struck me as Asian at times, though not so much her lips, and there is a large Indian diaspora in east Africa. Also in east Africa is an old ethnic influence from Indonesia, and even an Arabic influence. I couldn't place her at all, and my first guess was that she was from the Seychelles or Mauritius. She is gorgeous, though, and I think she'd be able to sell me anything, whereas I'd walk away from the more pushy ones.
