about my name..

Hi there,

My name is sahil kahin, and was born into the Muslim religion..
Everything looks fine so far, right ?
Well the question is that I'm not from India, as far as I can see, all my ancestors are from eastern Africa.
About 'Kahin' (My granpa's name), in this part of the world means something like one who does 'astrology' or something in the field of doing predictions about the
unknown or events in the future.
Sahil (my first name), I am told has something to do with the seashore, or the beach,.
Around here both names are considered to have an Arabic background.
