"MORDINGTON, a parish in the extreme east of the coast of Berwickshire ... The parish is bounded by the German ocean, the liberties of Berwick, and the parishes of Hutton, Foulden, and Ayton ...The present parish of Mordington comprehends the ancient parishes of Mordington and Lamberton ... The ancient Mordington was very small, comprising less than half of the united parish."
From the Imperial Gazetteer of Scotland, edited by John Marius Wilson, 1868.
The parish church (Church of Scotland) has registers dating from 1721. Old Parish Registers (before 1855) are held in the National Records of Scotland in Edinburgh, and copies on microfilm may be consulted in local libraries and in LDS Family History Centres around the world. Later parish registers (after 1855) are often held in the National Records of Scotland as are any records of non-conformist churches in the area (often unfilmed and unindexed, and only available there).
The parish registers available worldwide on microfilm include kirk session accounts for the years 1744-1767 (in part 752/1 of the microfilm). More information on kirk sessions and their records can be found in the Church Records section of the Berwickshire page.
Lamberton Toll in this parish was often a destination for runaway marriages (for more information on these runaway marriages see the Church Records section of the Berwickshire page). Indexes of some of the marriages at Lamberton Toll have been published:
Lamberton Toll Marriages 1804-1816 & 1849-1855 on microfiche by Original Indexes
Irregular Border Marriages, vol.1 - Lamberton Toll 1833-1849 by A.Brack. Available for example from the Scottish Genealogy Society
