The name Locklin is of Anglo-Saxon origin, derived from the Old English elements 'loc' meaning 'lock,' and 'hlyn' which means 'noise.' It was likely originally given to someone who lived near a noisy lock on a canal or river. The name first appears in records during the 13th century in England, but it is relatively rare and has not been widely used since then.
"Locklin was quite rare in 2019 with just five newborns sharing this unique name."
