I looked at Templeboy baptism register on National Library of Ireland site to get a better view.
I think that "Miriam" was actually "Mariam". Her name in secular life may have been Mary or Maria. Compare letters in her name with the word "filiam" (daughter). (See also "Mariam" baptised 25th Nov., higher on same page.) Godparents Michael Gallagher and Bridget Keoghanan.
Jacob translates as James. Godparents John Forbes and Maria (again possibly Mary) Gallagher.
Variations of Honora may have been Honor, Hanora, Ann, Annie and Nora(h).
Marriage registers 1815-1837 and unusually, some death registers from that era for the parish are on the NLI site. If Honora wasn't from that parish, look for a marriage in nearby parishes.
When looking at Tithe Applotment books, keep in mind that the names in them were a minority. Only heads of household who occupied agricultural land over 1 acre were included. The Michael Gallager who was in the Tithe Applotment book may not have been the same Michael who was godfather to Mary. The baptism sponsor may have been a brother or cousin of Honora. The Michael in Tithe Applotment book may have been Honora's father, grandfather, uncle, brother, cousin or more distant relative, or even no relation.
