Thank you for the replies - i should have mentioned that i've read the excellent 'Dragon Rampant' and have most of the accounts by other members of Ellis' unit

What i'm looking for, if they even exist, are any letters or a diary from Ellis himself that might have passed through to relatives.

Am now in touch with the Museum for the 23rd who may have something buried in the archive and will keep digging for a distant relative who may know something!

Many thanks Ben
