Walsall is one of those Boroughs that is located closely to other major towns, and I have found it difficult to place Cumpstons in the correct county as they moved across boundaries quite frequently.

"Walsall, an ancient borough, and well built and thriving market town, celebrated for the manufacture of saddlers' ironmongery, and other hardwares, is pleasantly seated on the crown and declivities of a bold eminence, surrounded by extensive mines of coal, iron and limestone, and distant eight miles N by W of Birmingham, six miles E of Wolverhampton and nine miles SW of Lichfield. On the north side of the town is a commodious station on the South Staffordshire Railway, and about two miles to the south is the small station of Bescot Junction, where that line is crossed by the London & North Western Railway. The Birmingham Canal passes the western side of the town to the Wyrley & Essington Canal, which has several branches extending into the parish.

Helen Norris kindly wrote to me that she knew a family of Cumpstons as a child. They were her next door neighbours, living at 225 Wolverhampton Road West, Bentley, Walsall. They were Samuel, his wife Miriam and their only child Jim (RJ) (who pre-deceased his elderly mother who had been widowed some years earlier). Sam fought in WW1; Helen still has his bayonet! Sam's claim to fame was being an official at the huge funeral of the founder of Rubery Owen (where he and her father, worked).

Sam gave her his bayonet when she was doing Bob a Job as a very enthusiastic Brownie, additional to the "Bob". He gave her the bob for cleaning it and then gave her the bayonet.
