Classic Irish boy names among the first wave imported to the US, such as Patrick, Kevin, and Brian, are still used in the US and Ireland along with other countries, but are no longer fashionable. If you want to name your baby boy after Grandpa Kevin, you might want to look to newer choices such as Kieran or Killian, which share the first initial K, or a more stylish name with a similar sound, such as Cian (pronounced kee-an).
