Margate is a town located by the see along the southeat coast of England. In the past, it was once a small fishing village, however it has grown to become a seaside resort. It is mentioned in The History of Mary Prince, in which Mary Prince accompanied the woman she was of service to (Mrs. Forsyth) to visit Margate after being with her for six months. Nonetheless, soon after, she was no longer of service to Mrs. Forsyth and was out of work. The idea of visiting Margate realtes to this idea that because of the social context, Mary Prince finds herself moving around very much as her service changes. 

"In the spring, I got into service with a lady, who saw me at the house where I sometimes worked as a charwoman. This lady's name was Mrs. Forsyth. She had been in the West Indies, and was accustomed to Blacks, and liked them. I was with her six months, and went with her to Margate. She treated me well, and gave me a good character when she left London" (Prince).
