"A parish in Berwickshire, situated in the midst of the Lammermuir hills, about 6½ miles in length, and 3 in breadth. The soil is light and dry, and, on the banks of the Whittader, fertile and well cultivated; but the hilly district is barren, and covered with heath. Here are the remains of the ancient abbey of Bernardines, founded in 1170, for which Ada Countess of March swore fealty to Edward I of England, in 1296. The Earl of Wemyss has lately built an elegant sporting villa, called the retreat, about a mile from the small kirkton of Abbay. Population in 1801, 138."
From the Gazetteer of Scotland published 1806, Edinburgh.
The parish church (Church of Scotland) has registers dating from 1715. 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).
