The senior NCO in the Irish Brigade that Casement tried to raise among Irish POWs in WW1 was a Michael Kehoe

I am researching the Irish Brigade and am trying to learn more about him

Apart from the fact that he was Private Michael P Kehoe in the Royal Irish Rifles and was captured by the Germans, I am struggling!

He appeared to be alive in 1932 when he attended the funeral of another Irish Brigade man Dowling
