General Register Office records for Mayo



Mayo broken down by Registrar's district

FamilySearch has indexes to 1958 for the Republic, to 1922 for areas that became part of Northern Ireland after that year, and birth register transcripts 1864-1881;
IrishGenealogy has indexes to 1916 for births (including mother's maiden name 1900-1916), marriages to 1941 and deaths to 1966. Images of the full records are available for all of these birth records, for the marriage records from 1870 and the death records from 1878.
In the Republic, most historic GRO records are online at IrishGenealogy.

A minority remains available by post or through the Dublin Search Room. See the Browse section for more detail.
