You're pretty close, actually :) Names derived from Hebrew were
fairly common in the Bible belt back when he was born. ("Haskell"
from השקל, wisdom. I half suspect "Curry" has a Biblical origin
as well, from קרי.)
Bible belt? Curry was born in Millis, Massachusetts, and grew up in Boston.
The word "Haskell" seems to occur much more frequently as a surname, originating in the British Isles. It seems more plausible that he got the name "Haskell" from some relative or family friend somewhere than ascribing a Hebrew origin for his name.
