★ What does Lachlan mean?

Usually explained as "from the land of lochs", an old Gaelic name for Norway

Scottish Gaelic, from Lachlann, linked to Lochlann, a name for Scandinavia.

Say it right

LOCKlan

In Scotland the "ch" is often breathy, as in loch.

The story of Lachlan

Lachlan comes from the Scottish Gaelic Lachlann. It is linked to Lochlann, the Gaelic name for Scandinavia, usually read as “land of the lochs” or fjords. The name is said to have first marked someone who came from Norway, a Norseman. Irish has the related name Lochlann.

Lachlan has long been a Scottish name, and it became very popular in Australia, partly through Lachlan Macquarie, the Scottish-born governor of New South Wales. The Lachlan River there is named after him.

Lachlan first appears in the CSO records in 1997, but it stayed rare until the 2010s. Its biggest year was 2016, with 18 boys in 2016, and its best rank came in 2019, when it reached number 262. The CSO counts Lochlann as a separate name.
