Good day clarysage,
Are you aware that some of the casualties listed on the Moor Row / Bigrigg memorials are also listed on neighbouring war memorials (e.g. Cleator Moor and Egremont)? There are a number of reasons for this, such as which religious denomination the soldier's family belonged to and moving house from one place to another.
For some years I worked as a volunteer for Cleator Moor Town Council to compile a 'Roll of Honour', some of whom are listed on the Moor Row War memorial. For example, if you click on the following link there are a couple of photographs and some information about brothers Rifleman John Young and Corporal Thomas Young who you, or to be more precise the Moor Row school children, would be interested in:

I saw the letter about this project in 'The Whitehaven News' as well and I was not sure from that whether it was just a WW1 project. The Cleator Moor Roll of Honour covers from the Boer War to the present day although the great majority of those listed in the book lost their lives in the 1914 - 1918 war.
Another thing you may like to try is to make an appointment for the school children involved in the learning project to visit the Whitehaven Archives Office and Local Studies Centre. This would be a good place for the school children to look at various relevant documents and 'discover' the information themselves in a structured manner.
Good luck with the project. It is extremely worthwhile.
