Quaker colonist (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
penn
'quaker colonist' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for penn that I've seen before include "US state (abbrev.)" , "William ---, Quaker colonist" , "Early Quaker leader" , "Colonising Quaker" , "Milk actor" .)
