Notes
A. ^ From 1923 to 1936, the FAI Cup was known as the Free State Cup.
B. ^ Attendances were calculated using gate receipts which limited their accuracy as a large proportion of people, particularly children, attended football matches in Ireland throughout the 20th century for free by a number of means. However, in this instance of a capacity crowd and the closure of the gates fifteen minutes before kick-off, this practice might not have been as common as usual.
