Hello Kate
Have checked mum's Birth certificate and it says the informant was B Sherry, Drumshannon. There can't be many female Irish names beginning with B so it's likely to be Brigid.
Have searched for info about Drumacoon school and others and have found this:
'Up to the building of Drumacoon school in 1903, one of the buildings at the entrance to Killeevan Chapel was used as a schoolroom.'
'In Slater's Irish Directory for 1894, two schools are listed for Newbliss, one in the village with a John Wallace as master and one in Clinmaulin with P Houston in charge.'
Killeevan Chapel and Drumacoon School were both RC, so perhaps the previous generation went to the school at Killeevan Chapel.
Were any of your husband's family interested in Gaelic football? I also have photos and information about Killeevan Sarsfields G.F.C.
I will contact you personally to send photos.
Kind Regards
Angela
