Adam de Lamberton gave a charter of a third part of his land of Lamberton to his grandson, Galfrido de Hasswell between 1190 and 1200. In the National Archives of Scotland there is a charter of Sir Peter de Mordington, knt., son of the deceased Sir William de Mordington, as superior, in favour of Simon de Baddeby of certain lands in Lamberton, dated 1270. A William de Lamberton was superior c. 1318.
Barony
Some records give Lamberton as a feudal barony; others that it became part of the vast barony assigned to Coldingham Priory..
Renton family
A charter dated November 21, 1325 of Agnes de Mordington, in favour of John de Raynton, thereafter designated as "of Lamberton", appears to herald the long possession of Lamberton by this family, descendants of the ancient foresters of Coldingham Priory. "Robert de Renton, Lord of Lamberton" was in possession in 1407. In 1632 David Renton of Billie held "the forty husbandlands of Lambertoun within the lordship of Coldingham". By the 18th century the Rentons had passed their ancient estate of Billie to the Homes, but retained Lamberton. The Rentons of Lamberton were in the early 19th century represented by Alexander Renton of Lamberton, who was served his father's heir in the lands and mains of Lamberton in 1774, and whose only child, a daughter Susanna, married Robert Campbell, a Colonel in the 42nd Regiment of Foot. Their son, Charles Frederick, Colonel in the 87th Regiment of Foot, hyphenated his surname. The Campbell-Rentons of Lamberton, and, later, Mordington House, also failed in the male line with the death in 1948 of Robert Charles Campbell-Renton.
Royal connection
The now ruined Lamberton Kirk was the church where, in July 1503, Margaret Tudor the daughter of King Henry VII of England, met the representatives of King James IV of Scotland, thus leading to the eventual succession of James VI to the English throne. Only ruins of the nave and chancel remain, as the burial-place of the Rentons of Lamberton.
Tournament
A tournament featuring knights from both England and Scotland participated in a tournament on Lamberton Moor to celebrate the marriage of Margaret Tudor and King James IV.
The now demolished Old Toll House at Lamberton, situated just across the border in Scotland, was notorious for its irregular marriages. From 1798 to 1858 keepers of the Toll, as well as questionable men-of-the-cloth used to marry couples in the same fashion as at the more familiar Gretna Green. The site of the house is marked by a plaque.
Smallholdings
Lamberton today consists largely of smallholdings compulsorily purchased, under an Act of Parliament, from the last Campbell-Renton laird, to provide a living for soldiers returning from The Great War. However, the land was not suited to crops, the holdings were too small for anything other than subsistence living, and today the original holdings are generally merged with others to make larger farms. Some modern house-building activity has taken place over the past decade along the original A1. There is no town or village, as such, just scattered housing, with views over the North Sea.
