Thank you for the info. While ALL my family lived on Staten Island at one time or another (except one)in the 1800 and 1900's, this question arose because of a work address of 85 Cliff St.in the 1859 Manhattan Directory. It was for a family who lived in Manhattan on 14th St. I could not find a Cliff St in Manhattan, the only one which came up was on Staten Island. Still puzzled.
