The only extant evidence that Kane Street in Cobble Hill used to bear a different name cam be found at the corner of Kane and Cheever Place. Look up and you'll be an old fashioned brick street marker that reads "Cheever" on one said and "Harrison" on the other. (You can't see if in the photo; my camera sucks and the letters are rather worn away.)
Harrison? Yes, Kane Street used to be Harrison Street. In fact, the historical Kane Street Synagogue used to be called the Harrison Street Synagogue. The change came in the 1920s, I believe. I don't know who Harrison was or who Kane was or why it was changed.
