Whitehaven is a cluster of wards that do not fit quite neatly onto the town plan. It may be best to include the built up part of Sandwith ward that nestles between Kells and Mirehouse. Also the settlement in Moresby (is it all called Moresby Parks?) is sliced in two by the ward boundary so it is best to leave it out of Bransty.
The individual wards are shown below:
Bransty (with Moresby Parks removed)
1. Bransty Road
2. The Green
3. Bleach Green
4. Harras
5. Extremities
(All these maps are at superscale compared to Keswick and Millom)
Harbour and Kells (temporary map, I will add walk squares)
6.
7.
8.
9.
10.
Hillcrest & Hensingham look like this. Walk squares to follow.
If you're on foot, it may make sense to take the built up part of Sandwith with Mirehouse. Walk squares to follow.
The whole of Mirehouse looks like this:
So there's really nothing South of Mirehouse Road. Walk squares to follow.
