The birth registry (https://civilrecords.irishgenealogy.ie/churchrecords/images/birth_returns/births_1875/03108/2140056.pdf) seems to confirm margaret Joy as the mother and the birth date as 17 Feb 1875. The district is Brosna but I cannot locate the townland. In any case, the western edge of that district borders Knocknagashel.
The church record shows the birth was a day later and the baptism on the 21st instant. The birth location is Cnocbeag and the baptism was in Knocknagashel.

The parents married in the first quarter of 1869 (Tralee, Vol. 1, p 740) The image is not yet available at irishgeneaology.ie but should be added early this year. Perhaps the image will show the name of the father of each. There were many church records for James Roche and many for Margaret Joy so without the name of the father it is difficult to know which records might match.
