[2] The chiefly family finally settled in Ayrshire, Dumfriesshire, Peeblesshire and Lanarkshire where they have held lands for over seven hundred years.

[2] A charter of 1323 is the earliest paper in the family archives, in which Sir Symon Locard bound himself and his heirs to pay an annual rent of £10 out of the lands of Lee and Cartland, South Lanarkshire.

[2] Symon Locard, 2nd of Lee, won fame for himself and his family in the Wars of Scottish Independence against the English when he fought alongside king Robert the Bruce and was knighted for his loyal service.

[2] In Spain, James Douglas had been killed fighting the Moors and command of the Scottish Knights fell upon Symon Locard, he then rescued the silver casket and heart.

To commemorate Sir Symon Locard's part in the crusade and the honour done to the family at some later date the name was changed to Lockheart and afterwards abbreviated to Lockhart.

[2] Sir Simon Lockhart captured a Moorish amir in battle and received from the man's mother as part of his ransom an amulet or stone with healing powers.

[2] The amir's mother told Sir Simon that the stone was a sovereign remedy against bleeding and fever, the bite of a mad dog, and sickness in horses and cattle.

[2] The dark red stone was later set in a silver coin which has now been identified as a fourpenny piece from the reign of King Edward IV.

The coin was exempted from the Church of Scotland's prohibition on charms and was lent to the citizens of Newcastle during the reign of King Charles I to protect them from the plague.

[citation needed] James Lockhart inherited the estates in 1777 and saw service on the continent where he rose to become a count of the Order of Maria Theresa and a general of that empress's imperial forces.
