My last name is Bostic and I have often been told that this is a Carribean surname. I am not sure which island, but I did live in Barbados for a period of two years and people would often comment that it is traditional from there. That name is from my mother's father and might have been transposed at the time of his death by my grandmother from Boston to Bostic. If anyone has any information regarding the my last name you may email me at email@example.com. Thank you.
