HERE is a link to the Military Service Pensions Collection (1916 – 1923).
It is part of the Military Archives from Defence Forces Ireland.
THIS link for example, shows an unsuccessful application
for a military service pension
from Grace Gifford, wife of Joseph Mary Plunkett.
And THIS one includes a successful claim for
Donagh and Barbara MacDonagh,
who were orphaned 9 July 1917
when mother, Muriel MacDonagh nee Gifford, drowned.
Their father was Thomas MacDonagh.
