Yes, I see that usage of 'hooker' was mentioned in a 1956 book called 'Tarheel Talk' and dated in that at 1845. I originally picked up the connection with Fighting Joe from a reference in Gore Vidal's 'Lincoln' and he refers to the use in Washington at that time of 'Hooker's girls'referring to his stream of visitors. I understand that the late Civil War historian, Bruce Catton held Mr FJ responsible for popularising the term and recorded that the Washington red-light district became known as Hooker's Division. Obviously Fighting Joe was a man of prodigious talents.

I stand, gratefully, corrected.
