One of the biggest problems with the Stackhouses in Pelsall is that each generation used the same for names, all the cousin used the same names. There are a few single exceptions but they don't always help a lot. You can bet that you will have a William, Mary, James, Samuel etc you need to identify and he/she will have several cousins born around the same time too with the same name.
Noting your question about Pelsall Common. Imaging a London Park shaped like a triangle. All along the outer roads bounding the common you have houses that face onto the common. The same goes for the smaller common to the north.
If you google old maps, the first entry will give you a wealth of maps to search going back to 1884. These will give you an idea of the layout. There is also a Stackhouse Lane leading off one of the commons too.
Back to Mary. I have Mary's maiden name as Phillips too. Is that what you have?
