Hi
I can see two possible baptisms
Margaret o'Keefee d of John and Mary Kellegher 16/21 Nov 1869 Douglas Ballygarvan, Douglas and Ballygarvan
Margareta O'keeffe do of Johnnais and Maria Fitzgerald 7 Nov 1870 at Dunmahon Glanworth and Ballindangan
Sorry but I don't know the area and can't tell which would be the most likely.
