This is an old post, but I found it because I was searching for maps for the Progeny Press guide to Johnny Tremain.
Thought I'd post a few links that helped a bit:
Fish Street and Hancock's Wharf shown on this map: http://historygallery.com/maps/NorthAmericaMaps/1775Boston.htm
Older map 1723, shows a larger area but Hancock's Wharf is not labeled as such:

Also note that "Fish Street" as "Fifh Street" -- the "f" is that colonial "long s".
Hope this helps someone else - it was a bother to hunt them down :001_smile:
