How to choose

A two-syllable first name often pairs well with a longer or shorter surname, while a single-syllable name like Sean or Shane can provide balance beside a multi-syllable last name. Consider the vowel sounds — names like Liam and Cody have softer, more open vowels, while Patrick and Connor carry firmer consonant sounds. The meaning may also matter to you, whether you're drawn to a name that speaks to protection, nobility, or kindness. You can explore names by sound to compare how different options feel side by side.
