Meaning & origin
Locklyn is a modern feminine name that emerged in the United States around 2011. It reached its peak rank of 7,491 in 2014, after which its usage has gradually declined. As of 2025, it remains a rare choice, given to roughly 1 in every 114,805 babies. The name likely draws on the Irish surname Locklin, combined with the fashionable -lyn suffix, reflecting a broader trend of surnames and traditionally masculine names being adapted for girls. While its etymology traces back to the Gaelic Ó Lochlainn, Locklyn itself is a contemporary coinage with no deep historical roots. It has not been consistently recorded in any particular state, making it a truly uncommon pick nationwide.
Locklyn is a modern variant of the Irish surname Locklin, itself an anglicization of Ó Lochlainn, meaning 'descendant of Lochlann,' a personal name derived from 'loch' (lake) and 'lann' (land). The name has been used sparingly in the United States, likely influenced by the trend of surnames as first names and the popular -lyn suffix for girls.
