Hi
No Water Lane yet, but I've found John Wood's 1821 Map - before the railway - or a piece of it anyway.
He has Water Street and Water Gate Lane. How to explain? It all looked different!
If you think English SDtreet carried on to the top of Botchergate, before the cutting was made to go over the railway, when you get infront of where the station os now, The Crescent was then Court Crescent, and that had almost another half circle facing it where the station forecourt is now.
on the left, Collier's Lane still cuts through the hotel, parapllel to Botchergate. Where that opens onto Court Square, a street, Water Street, carries on straight through the Station. In fact I wonder if the first few yards are what goes acriss the lights from the Crescent to the station now.
It goes straight through and comes onto Water Gate Lane which looks as if it runs in front of the modern Matalan etc and Brown's Row - Old Cottages still standing? - and sout out of town. It starts at Caldew Brow.
You could also contintue from the end of the named Water Street across Water Gate Lane and over the river thento the left along the river to Long Island Cotton Factory. This unnamed bit just dotted. Wayer Lane?
Could Water Street have been along the exit of Matalan and over into Boustead's? There's a Bridge there. Too far down?
As for Water Lane, is this a red herring, or getting warmer?!?
Good Luck!
