The parish included part of the village of Patna which developed in the early 19th century beside the Doon and astride the parish boundary with Dalmellington.
In Straiton churchyard rest the remains of Thomas M'Haffie, a native of the parish, who, after repeated escapes from the hands of the troopers, was at length captured and shot on the farm of Linfairn. A memorial stone, which was erected in 1824, alongside of the old one, bears the following inscription:
"Here lies Thomas M'Haffie, Martyr, 1686.
Though I was sick and like to die,
Yet bloody Bruce did murder me,
Because I adhered in my station,
To our Covenanted Reformation.
Ay blood for vengeance yet doth call
Upon Zion's haters all."
Thomas M'Haffie was the son of a farmer at Largs, near the village. He had hid himself in a glen on the farm of Linfairn, but, being seized with fever and having taken refuge in a house near at hand, he was dragged out of his bed and shot on the road.

The parish includes the Blairquhan Estate and House. Blairquhan House was built between 1820 and 1824 in a Tudor-Gothic style on the edge of the plateau on which Straiton stands. The house and gardens are occasionally open to the public during the summer months. Above the village to the east, a monument stands on top of Craigengower (locally referred to as 'Monument Hill') commemorating Colonel James Hunter Blair of Blairquhan who died at the battle of Inkerman in 1854.
At the northern tip of the parish, lies the village of Patna. The village was originally a mining community which belies its exotic name (with unsubstantiated links to India). The village housed miners of the Waterside and Dalmellington pits, but the mines have long gone. The village itself has expanded considerably over recent years, as the smaller hilltop mining communities such as Lethanhill and Burnfoothill were moved into council or coal board housing in Patna. Patna now has a small knitware business. It also has a small 9-hole golf course.
An 1837 description of Straiton and Patna, including a listing of the key personalities of the villages, is given in this extract from Pigot's Directory for Ayrshire. The transcript was provided by Keith Muirhead from Queensland.
To the south-east of the parish is the county boundary with the Stewartry of Kirkcudbright and the Parish of Carsphairn.
