There's quite an interesting debate going on over at Canalplan about the names of the three locks on the Hertford Union.
Canalplan uses the names given in Edwards so they are Old Ford Locks. Other sites (including wikipedia) use these names but it looks like they've used Canalplan as their source. C&RT refer to them as Top, Middle and Bottom Locks, Hertford Union (most of the time.. .they also refer to them as Old Ford Locks)
I've found that Stanford's map of 1872 refers to the middle lock as Wick Lane Lock...
So does anyone have any other sources which either are contemporary to Edwards or that pre-date Canalplan going on-line (so say prior to 2002) - examples being old guide books etc, that might shed some light on the subject?
