The CSO has revealed the most common surnames in Ireland

Theodore and Ivy have become popular children's names.

Kelly, Murphy and Ryan were the most registered surnames among babies in Ireland in 2018 according to the Central Statistics Office (CSO). New data released by the CSO on Wednesday revealed the trio of surnames topped the list in 2018 with Murphy being registered 686 times, Kelly 584 times and Ryan 498 times. When it comes to first names, there's been a few interesting additions to the top 100 most popular names in Ireland. For the boys, Frankie, Theodore and Freddie have all made the leap into the top 100, while for the girls Ada, Bella, Bonnie and Ivy have done the same. Jack is still the most popular name for boys and Emily is still number one among the girls. While the population of the country is not far short of the five million mark, the number of births are falling. The CSO estimates the population of Ireland is 4,921,500 with women outnumbering men by 2,483,500 to 2,438,000. It seems that 2018 was a less fertile year than the year before, as there were 61,016 births registered in 2018, which is 23.2 percent lower than 2017.
