Thanks, Shaun!
That's fascinating. I'm now trying to decide if I'm confused or if everything has just become clear.
Clipsley Lane is below Judge Field Brow on the map. As far as I'm aware, Clipsley Lane has always been in Haydock. I have members of the TWISS family living on Clipsley Lane in Haydock on the 1841 Census.
On this map you can see Old Florida and Old Boston north of Judge Field Brow. And there's rather helpfully a label of Haydock near Old Boston. Again, as far as I know, Florida and Boston have always been in Haydock.
So, as Judge Field Brow is above Clipsley Lane and below Florida, doesn't that mean that Judge Field Brow is in Haydock?
If I'm missing something obvious, feel free to point it out

P.S. What year is this map from, please?
