Was he in the Salford Pals, Dave? The Salford Pals : The History of the Salford Brigade, the 15th, 16th, 19th and 20th (Service Battalions the Lancashire Fusiliers, 1914-1919) by Michael Stedman sounds interesting.

And you'll have no doubt seen Lancashire Fusiliers Museum website

Good luck! My husband's grandfather was with the Leeds Pals and died from injuries received at the Somme. Husband has done a fair bit of tracing.

Good luck.
