"A parish in Berwickshire, of a triangular form, each side of which is about three miles in length. The soil is mostly clay, lying on a cold impervious tilly bed; but there is a considerable extent of gravelly and sandy soil. The greater part is inclosed. The principal crops are oats and barley, a few pease, and sometimes a little wheat. There are several extensive woods and plantations. The village of Polwarth, which contains about 200 inhabitants, is situated on a very wet and swampy piece of ground. In the middle of it are two old thorn trees, at about 6 yards distant from each other, around which it was formerly the custom for every new married pair, with their company, to dance in a ring: from hence the old song of 'Polwarth on the Green'. But this custom has fallen greatly into disuse. Population in 1801, 291."
From the Gazetteer of Scotland published 1806, Edinburgh.
The parish church (Church of Scotland) has registers dating from 1652. 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 1747-1771 (in part 754/2 of the microfilm). More information on kirk sessions and their records can be found in the Church Records section of the Berwickshire page.
