And could this be same child (although age is 10 years out)?

No. Elder sister.
Baptism Kilteevan, (adjacent R.C. parish to Athleague) 19th Nov. 1852.
Sponsors Michael Brinan? (Maybe Brennan as spoken in local accent) & Ann Scully
Parents' marriage same parish 29th March or April 1840. Last marriage on previous page was mid-March, followed by a note that the bishop had visited. Next page has 2 marriages followed by May marriages. It was the general custom not to celebrate weddings in Lent, hence the rush of weddings in February -early March that year. Easter Sunday was 19th April in 1840 so wedding was most likely 29th April. John's surname looks to me like Shruan but it may be faded ink. Witnesses Luke (can't read surname) & Mary Scully.
John and Elizabeth had witnessed wedding of Luke Flanigan ? & Ann Scully at same church 24th. Feb. that year. John Shr..an?
That may have meant dowries for 2 Scully daughters in a couple of months.
https://registers.nli.ie/parishes/0564Kilteevan was presumably Elizabeth Scully's home parish. She may have gone there for the birth of daughter Elizabeth 1852 so that female relatives could care for her or she may have been visiting family when baby arrived.
