ALLEYN (ALLEYNE/ALLEN) baptisms in Golden, Tipperary

I've made a few posts on the ALLEYN family, and have put a lot of effort into the farther-back origins of the family, and they can be summarized as follows: Samuel ALLEYN(E) married his wife Mary HAMMOND in Ireland probably around 1830 and they had at least seven children together in the village of Golden, Tipperary, Ireland before the family sailed to Australia, arriving 1850 on the 'Thetis' and settling in Sydney in the city then Glebe area after Samuel had died. The eldest daughter Elizabeth actually arrived earlier in 1850 separate from the rest of her family. Here are the off-spring:

I knew all family members were born in Golden and were Roman Catholic from their immigration records, but knew nothing more than that as access to Irish parish records is limited.

I was very pleased to recently find that Ancestry.com has made available the scans of parish records for 'Golden and Kilfeacle' parish (which seems to be the name of the modern parish). Looking at these I found the following baptisms. I will not past the pages for each page of the parish book, just the first, then all the transcripts.

1850 Jan 13, William Allen of Golden received into the Church
1850 Jan 14, Mary of Samuel Allen and Mary Hammond Golden, sponsor ?? Ryan ??

So there are a few questions - mainly what happened in 1850? Was this the baptism or confirmation of Samuel and William aged 11 and 17? Or was it the baptism of the father converting from Protestantism? And where are the baptisms of the other children? I assume in the latter case I can't find them due to transcription/reading challenges. The writing on some pages is truly a scrawl.

At any rate, it is rare to take an Irish family that arrived in Australia back into primary records in Ireland. Most enjoyable is that the name is written ALLEYN with a 'Y' when my direct ancestor Ellen was baptized. The spelling is so variable for this family, so to see the 'correct' spelling used in Ireland help me understand how they saw themselves.
