Continuing with my research into the names of the fallen on the internet I came across a web page on Derbyshire War Memorials. It has the names, regiments and some brief family histories for some of the men.
This will be at least a good starting point for the Military information. I need to double check everything with census, parish records and military records as the sources aren’t listed and therefore need checking. However, it has given me quite a few reference points to start with.
The web page if anyone would like to have a look can be found here
