What Lochlainn Means

Lochlainn means land of lakes or fjords. Irish speakers used Lochlann for Scandinavia, particularly Norway, so a man called Lochlainn was a Norseman — the name is an ethnic label rather than a description.

Where Lochlainn Comes From

Lochlainn is the Irish spelling of the Gaelic Lochlann, from loch, a lake or sea inlet, and used from the Viking age as the name for Scandinavia — a country seen from Ireland as a place of fjords. The name entered Irish and Scottish use during the centuries of Norse settlement, when intermarriage between Gaelic and Scandinavian families was common. The Irish form gives the surname Mac Lochlainn, anglicized MacLoughlin, and the Uí Néill branch of that name supplied several High Kings. Scotland's Lachlann gives Lachlan, which dominates in Australia through Lachlan Macquarie. Lochlan with one n is a modern simplified spelling, and Lochlainn, Lochlan and Lachlan all rank separately on record.

Irish figures withhold any name given to fewer than three babies in a year, so a gap means the name fell below that floor rather than went unused. The Central Statistics Office began recording the síneadh fada in 2018, so accented and unaccented spellings are counted separately from that year on. Data & sources.
