We have the same oral tradition in our branch. I have mentioned it when visiting temples in describing my ancestry with Jewish friends and to my nieces and nephew whose father's family is Hungarian American Jewish. Whether she was entirely Jewish I do not know as there are stories indicating she too was part Asian. The probability due to those families claiming us as relatives through her is that she was. Indeed Grace seems from one of the Sephardic Jewish families that were then warehouse operators in Oranjestad. They were mostly constructed in the 1700s during the French and English War and the American Revolution boom years. That stopped with the British invasion under Rodney and Hood. They have slowly crumbled but were useful for cheap long term storage for many subsequent years. http://www.ecm.net/hsrj.de/statia/s60.jpg
