Bridget McDonnell, Full age, spinster, Shopkeeper (Rineen crossed out), living in Rineen, father Jeremiah McDonnell, butcher
Witnesses Honora Donovan and Margaret Minihane.
I think it is likely the birth sponsor and this McDonnell are related given the same parish and not too many of that name.
I have details of the census's for these people in 1901 and 1911, and possible deaths for two.
