Hi
I have just discovered Hubert's Pension record on Anc, indexed as Herbert born Herefordshire...... Hey ho.

Some info that might help, he attested into the Leinster Regiment 24 Aug 1901 at Clonmel aged 18. At this time he was already in the 4 Royal Irish so presumably Mum Mary & Hubert must have returned to Ireland before 1901.
He served in South Africa & Mauritius then joined the British Expedition Force in 1914, served in France until 1917.
In answer to your question Jackie, Hubert married Mary Ann Steffernan 8th Oct 1911 in Clonmel. That's probably why her name is added at the bottom of "next of kin".
Hope you have all this info bgoodman, if not let me know.
