The CSO has also provided a breakdown of the most popular baby names by county for 2018. Noah was the most popular boy's name in Sligo and Cork city last year while Jack claimed the top spot in Dublin city, Dún Laoaghaire-Rathdown, Fingal and south Dublin.
Adam and John were the most popular names for boys in Leitrim while Daniel proved the favourite in Limerick city.

Jack was the most popular name for boys in 2017 with 685 babies registered, followed by James (619), Daniel (536), Conor (472) and Sean (453). Emily was the most popular girl’s name in 2017 (459), followed by Emma (393), Grace and Amelia (both 371).
Mary (3,471) was the most popular girl’s name in 1964 while John (3,696) was the favourite for boys.
Carol Anne Hennessy, CSO statistician said: "Back in 1968, John, Patrick, Michael, James and David were the names most favoured by parents of new born baby boys. While there were 2,863 baby boys named John 50 years ago, the five most popular boys' names in 2018 together accounted for 2,691 baby boys.
“Interestingly, not one of the top five names for girls appeared in the top 100 names a half century earlier. Mary, Catherine, Margaret, Ann and Anne were the most popular names for baby daughters in 1968, with 2,364 baby girls named Mary in that year.
“In 2018, there were 460 baby girls named Emily, 19.5 per cent of the number of girls given the name Mary in 1968.” The CSO said over the years girls have been given a wider variety of names than boys with 4,779 girls names registered compared to 3,712 boys.
