John Flaherty was another name that was hard to trace. It was only a long process of elimination that lead me to a possible identification. Please see this recent forum thread:

His connection to Ibstock seems slight. He does appear in the 1911 census living at 123 PRETORIA ROAD IBSTOCK LEICESTER as a lodger. He is described as a miner, born Longton Staffs of 21 years age.

His RND record summary from the Jack Clegg Memorial Database adds very little:

Name: John Flaherty

Service Branch: Royal Marine Light Infantry

Unit: 2nd Royal Marine Bn.

Rank: Private

Death Date: 7 Jan 1916

Cause of Death: Killed in action

Burial: Skew Bridge Cemetery, Helles (Gi 14)

Notes: Son of Mrs. Ann Flaherty, of Elmare St., Rugeley, Staffordshire.:

I'm not hopeful that there is anymore at the Fleet Air Arm Museum. As a small footnote, I have since learnt that Michael Dolye's book has the same identification for J.Flaherty.

There was one other clue, which I have yet to talk about.
