Since each entry holds at least the names of the bride and groom, the number of names in the database is growing fast. This latest upload brings the current total to nearly 100,000 names. All entries pre-date 1864, when civil registration of ALL marriages in Ireland started.
The Early Irish Marriage Finder Index was launched a year ago and is unique to the IGRS. It is free to search here, but do read Roz McCutcheon's Introduction to fully appreciate how the Index works and the sources consulted.
