This list has 51 POWs in the Irish Brigade. The 3 senior NCOs , Keogh, Quinlisk and Dowling were missing plus Wilson and Sewell.
It is a list of POWs transferred from Limburg to Zossen on 28 Jun 1915
Oddly the numbers 21 and 22 are missing from the list, and I suspect that they are Sewell and Wilson lost in transcription somewhere.
