Granny Butler (as known after she married Jack) even had 4 of the Quinn children live with her as the family grew larger.
Is Granny Butler Mary MASON?
If so who were the QUINN children? were they John, her first husband's children, or her grandchildren through Michael, or other extended family?
The only additional information I have found is that in 1895 there are a John QUINN of Ballybrack and James MASON of Loughlinstown listed in the court sessions for what looks like the same incident on Dec 8th 1895 in Killiney. They were Drunk and Disorderly and there was damage to a "panel in the barrakcs door". James' charge was dismissed without prejudice but John was fined 5 Shillings. James seems to have had several D&D's over the years and a couple of stays in gaol when he defaulted on the fines.
Ages did go askew in those years and if John QUINN was older than Mary then he maybe the man who died in Rathdown in Apr-Jun 1905 V2 P684 aged 40; there are also a handful of options in Dublin South from 1902 to 1910 with DoB's from 1860 to 1875.
I am not sure of the churches in that area but someone local may be able to tell you if there was a convent with attached chapel or church that closed. This could account for unrecorded records; I found this with St. James' parish in the city centre.
