"The name 'Fala' is derived from the little hill upon which the parish church stands, and is a contraction for FAULAW, FAWLAW or FALLA. It is the same FAL or FAW which is found in Falkirk, Falkland and Fauside, and means 'speckled', hence Fala means 'speckled hill'.
Soutra, spelt SOLTE, SOLTER, SOWTRAY, SOUTRAY, means in Cambo-British, 'prospect town'. No doubt the name arose from the magnificent view which is got from the site of the ancient monastery, which was at the time surrounded by a considerable village.
Fala & Soutra forms the south-east corner of the county of Midlothian and 15 miles from Edinburgh. Fala is bounded on the east by the parish of Humbie; on the south by the parish of Soutra; on the west by Heriot and Stow; and on the north by the detached parts of Borthwick, Cranstoun and Humbie and by an attached part of Crichton parish. It is about 5 miles long from E to W and 1 mile broad N to S and contains about 3120 imperial acres.
Soutra, which is almost the same length and breadth, lies immediately to the south, in the county of East Lothian, having Channelkirk for its southern boundary, and containing about 2940 acres."
