Jack and Aoife were the most popular babies' names last year, according to figures released by the Central Statistics Office today.
There were 846 boys named Jack (3.3 per cent of boys) and 633 girls named Aoife (2.7 per cent of girls) last year.
Conor - 1999's most popular name for boys - is now third most popular, while Chloe, the most popular girls' name in 1999, was fifth most popular in last year.
But Conor remained the first choice for parents in the Border region with Chloe the most common first name for baby girls in the south-east, the CSO figures show.
New entries in the list included: Josh, Dara, Kian, Amber, Zara, Cara, Charlotte, Lara, Orlaith and Taylor.
The results are based on an analysis of the first names recorded on birth returns for registration and vital statistics begun by the CSO in 1998.
