I don't know how I missed these at the Lyeberry of Congress site!
Go to
http://www.loc.gov/pictures/item/NJ1222/ and find 93 of 'em - and you can download HUGE detailed copies.
(Funny seeing it called "in Essex"; I suppose that's the county. Amd why are NJ municipalities so itsy? Seems like you walk 1 mile in any direction & there's another place: Orange, South Orange, West Orange, East Orange! )
