Cummertrees, recorded as Cumbertres in 1204 and 1207, is probably of Cumbric origin. The second element represents *tres 'strife, tumult, violence', cognate with Welshtres and Gaelictreas. The first element is *cümber, cömber 'confluence. Andrew Breeze proposes the meaning 'confluence of turbulent water'. Alan James suggests that *tres may have been a stream-name. However, James notes that the first element may represent *cömbröɣ, which occurs in the name Cumbria.
History
Cummertrees is rural, primarily residential village; the parish includes Powfoot and Trailtrow and is bounded by St Mungo and Hoddam, Annan, the Solway Firth, and Ruthwell and Dalton. A Public hall was erected at Cummertrees in 1893. The river Annan is at the northern boundary. It has a wide area of level sand swept by the Solway 'bore' which can move at around ten miles an hour and can often be heard throughout the parish. The seaboard is low and sandy and features in Walter Scott's novel Redgauntlet. The ground rises a little inland, to on Repentance Hill. The local geology is mainly Devonian, with old limestone workings at Kelhead and some sandstone quarries. In a field called Bruce's Acres, at Broom Farm, Robert Bruce fought and lost a skirmish against the Southron. Cummertrees parish includes some notable buildings, Hoddam Castle, Kinmount House and Murraythwaite. Historically, the main landowner has been the Marquess of Queensberry. A nearby caravan park has been named in his memory. The church was founded by Robert Bruce and has been much rebuilt and enlarged. The Douglas Family Mausoleum at Cummertrees parish church is traditional burial place of the Marquesses of Queensberry. There is also a private family burial ground dating from the mid 19th century for the Queensberry family on Gooley Hill within the policies of Kinmount House.
Kinmount House
was the seat of the Marquesses of Queensberry, described by Groome in 1903 as a beautiful edifice, built in the early part of the 19th century at a cost of £40,000, and surrounded by fine pleasure grounds.
Lord Francis Douglas was a British mountaineer born in Cummertrees. After sharing in the first ascent of the Matterhorn, he died in a fall on the way down from the summit, aged just eighteen.
Steve Ovett lived at Kinmount House from 1988-1998.
