"A parish in Berwickshire, about 10 miles in length, and 6 in breadth, extending along the foot of the Lammermuir hills, and into the flat country of the Merse ... It is watered by the two rivers Blackadder and Whittadder, which here unite near a hamlet called Allantown. The celebrated mineral spring called Dunse Spa is on the borders of this parish, where its march runs with the parish of Dunse. The greater part of the land is well inclosed, and drains have carried off several small lakes and marshes, with which the face of the country was formerly much disfigured. Population in 1801, 1355."

The Borders Family History Society has published a CD of Edrom monumental inscriptions. This includes photos of the gravestones, as well as other resources such as the 1694 hearth tax, 1695 poll tax, early 1800s militia records, late 19th century school admission lists, and war memorial and roll of honour details.
Pre-1855 inscriptions for the parish are contained in the Scottish Genealogy Society's volume of Berwickshire Monumental Inscriptions (Pre-1855).
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 Borders Family History Society has published Full of Egotism: being the diary of the Rev. John Hastie, Minister of Edrom Parish Berwickshire, 1797 to 1822.

As well as mentioning his friends and relatives the diary has numerous references to local people, events, and lists many baptisms, marriages and burials that Rev. Hastie performed.
