Information note: The CSO’s Irish Babies' Names 2021 publication includes the síneadh fada and other diacritics since it was first introduced for names registered in 2018. This change has resulted in a break in the series, with new entries created for names with the síneadh fada and other diacritics.
This has an impact in the order of the popularity of some forenames. For example Sean (without the síneadh fada) has always been in the top 100 most popular names for boys. Seán with the síneadh fada is now included in the data and both spellings are treated as 2 separate names since 2018, thus Seán has a rank of 16 while Sean has fallen to rank 102 in 2021.
