Liam has been a UK top 100 staple for over 20 years. Finn cracked the top 100 in 2022 and has stayed there. Rory is rising fast, reaching #24 in 2024.
Irish girls' names tend to have the most unusual spellings in English — Aoife ('EE-fa'), Niamh ('NEEV'), Siobhan ('shih-VAWN'). Many parents choose them specifically because they tell a cultural story. Both rank comfortably in the UK top 250.
