Hi maddys I will follow up on that, now that a lot of information has been gathered on Samuel FRANCIS.
From the newspaper reports etc, he has a birth region (place) as Hindostan, Madras, India Generally and described as Chingalese, and just mentioned as a Coloured Man.
At least I have a general birth year and the photo from his time/times in gaol could be very useful. Many thanks Dianna
