Hello,
Thank you for the reply.
Sgt Peter Wallace was shot on a train in Co Limerick, he was from Co Roscommon, just outside Strokestown, and is buried in Bumlin Cemtery, Co Roscommon. Some of his distant relatives still live nearby.
His death was mentioned in several newspapers, and it is mention in Police Casualties in Ireland 1919-1922, by Richard Abbot.
Have you gone on the 1901 Roscommon Census?, if your family are on that, you should should try the Griffiths Valuation and you should be able to pin point the exact house they where in using the map with valuation.
Funnily enough I was in Gortoose before looking the old RIC barracks that was there, but it had been demolished. Gortoose Townland looks out onto Slieve Bawn mountain.
Regards,
Kliffy.
