Ben Franklin's birthplace (6)
I believe the answer is:
boston
'ben franklin's birthplace' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for boston that I've seen before include "Card game; Lincolnshire town" , "Lincolnshire town - tea party venue?" , "American city that once had a famous Tea Party" , "Mass housing this" , "cards" .)
