Clan Leslie Society
Australia & New Zealand



The More/Moore sept is by far the largest of the Leslie septs. The name More is probably taken from the Celtic word 'mor' which means great or large. It is possible that the first Mores were Scots from Northern Ireland who, in the 6th century, left Northern Ireland to found the Kingdom of Dalriada in western Scotland.

The Laurus Leslaeana (1692 by William Aloysius Leslie), the first chronicle of Leslie history, states that the earliest connection between the Leslies and Mores happened sometime during the mid 13th century. The connection being the marriage of Bartholomew's third successor and Catherine More, the heiress of Tasseis of Fife. There have been later sources which dispute the time of the first connection between the Leslies and the Mores.

By all accounts the Mores are a sept of the Leslies, however, some Mores are septs of the Campbell's and the Grants. The Mores were, at one time or another, tenants of both the Campbell's and Grants.

Some of the noted Scottish Mores in history are Thomas De La More who was the counselor to the Celtic Queen Devorguilla, the mother of Scotlands King John Balliol. The most notable of the Mores during the Renaissance was Sir Thomas (1478-1535). Sir Thomas was Chancellor to King Henry VIII who had him beheaded.

Sir John Moore (1761-1809) became one of Britain's best field commanders. His most notable (and last) victory came at the expense of Napoleon during the Peninsular Wars in 1809.

Many other Mores have gained world recognition throughout history for their contributions to the fields of literature, the arts, sciences, and many others. However, possibly the most important contribution to society came from Clement More. Without Clement More we may all have a completely different vision of Christmas! Clement wrote 'Twas The Night Before Christmas'.
