PS to my reply #8, having now examined previous and subsequent pages, content confirms what I thought.
Baptisms 'P.P.':Child's forename + surname; father's forename; mother's forename; mother's surname.
Baptisms p and a squiggle: Child's forename; father's forename + surname; mother's forename + surname.
P.P. did majority of baptisms. There were normally 42 per double-page. 9 on the double-page where Mary Allice's baptism is were by p squiggle. Only exception to this pattern was 3rd Nov. 1865, Margaret, parents Denis May & Rose Milligan. Handwriting is not like P.P.'s ; someone else (p squiggle?) may have written it in , perhaps from a note left by P.P. and wrote it his own way.
P.P. did 38 of 42 baptisms on previous double-page March-July 1865; p squiggle 4.
P.P.'s baptism rate had dropped to 29 out of 42 for April-Dec. 1866, p squiggle had 13.
I surmised those without 'P.P.' might have happened on his day off. However on 20th May 1866 there was a baptism by P.P., entry with his usual format and one with p squiggle, in his style & scrawl, with a line separating them.
If baptisms in the p squiggle format were all illegitimate births, the priests would be having a moral panic, so imo, they weren't all illegitimate.
There's a note on 17th Feb. 1868 in the marriage register 'Father Geoghigan died this morning'. Marriage register is fairly neat. I wonder if Father G's baptisms were p squiggle's.
