Origins of Loch:
According to the early recordings of the spellings of the surname, this interesting and unusual name was listed as Loch and Lough. It is Scottish but from the 17th century as Lough, it is also well noted in Northern Ireland. It is habitational and shows to explain a resident by a lake, generally a water filled Dale, sometimes connected with the sea. Probably, surprisingly as both Scotland and Ireland are full of lakes, and according to Black's Surnames of Scotland, the name is said to have a particular place of origin. If correct, this is Portmore Loch in the church of Eddleston in Peebleshire. Originally, the first documentation is from this region with that Reginald of the Loch who for some reason gave up his marriage and his estates in about 1214. Other recordings of that time contain as Walterus de Lacu, a name recording which is a combination of Latin, French and Old English, a witness to a document confirming lands to the priest of Neubotle in the year 1230 A.D., although this seems to have nothing to do with the old estate loss. However, it looks like for the next two centuries, the family wanted to regain their lands, although without much success. In 1296, one Malise de Loughs was taken by conflict by the English and held in Dunbar Castle. Apparently, he was of some value, because he was allowed "monies." Finally in the 17th-century named ancestors got the estates of Drylaw in Midlothian, and also the estates of Rachan in Peebleshire.
