In the back of my mind I had been wondering if Granville Terrace were railway cottages, the railway company might have had to buy all the land and therefore utilised it?

Just to qualify this, the Cheshire Tithe are quite a bit inaccurate on the relative placement compared to the modern map, it was the NLS maps which I was referring to.

Wood Ln on maps today are the backs of the houses on Marshlands Rd and Wood Ln.
Where you access the front of the houses in Wood Lane there is a footpath that is also called Wood Lane.

I din't make allowance for the nonsense the council get up to - there was a reason we used to have roads called things like "Back Wood Lane".

I didn't have access to streetview the other day to have a look.

The wall to the east of everything called Wood lane looks a fair old age!

Here is an image from 1946 off 'Britain from Above' and you can clearly see that wall at the end of the Wood Lane footpath..
You can also see the 5 pairs of semi-detached houses on Mashlands Rd still standing today.
So if that footpath is Wood Lane, there is two roads between Wood Lane and Marshlands.
Which one is Granville and what is the other?

Obviously need to login to zoom in

The first row (nearest) of houses is the east side of Granville Terrace

The second row is the west side of Granville Terrace which are bang on top of the existing Wood Lane roadway.

Then there is a gap which includes the un-named lane which maintains right of way to houses further down.

The third row of houses is the east side of Marshlands road which may be the ones that still exist today, if so these were built before the west side.

The fourth row of houses are the west side of Marshland's road which as you say still exist today.

The more I look at this the more it looks like the un-named name was the original Wood lane which included the straight on extension and the 90 degree turn to Wallasey Village Road. Apart from Marshlands Road the rest was completely hashed up When the modern Wood Lane was created.

I see your notes on BFA for clarity DD.

I always intend to do more on there but there just aren't enough hours, I also input on OpenStreetMap and edit Google maps.

Here's what it looked like if it helps...

Nice pic Winston.
What year is it? It looks like it will be getting demolished not long after that picture, going by the amount already bricked up.
