Originally spelled as Lockard or Lokart, the Lockhart family would arrive north from England after they had been dispossessed of lands by William the Conqueror in the 11th century.
The family would first stay near Annandale in the south of the country and the town of Lockerbie near the English border is said to have been named after them. The chief family would eventually move again and settled in Ayrshire and Lanarkshire where they would hold lands for over 700 years.
During their time in Ayrshire and Lanarkshire, they would construct Lee Castle, one of the grandest clan seats still in existence to this day. The castle remained under the ownership of the Lockharts until 2004 when it was surprisingly put up for sale on eBay and eventually sold to a private American buyer.
The clan still possesses significant lands near their old seat at Carnwath. The current clan chief is Ranald Lockhart of the Lee, Chief of the Name and Arms of Lockhart.
