Some masonry quoins from the tower decorated with characteristic Scottish renaissance buckle carvings were used in the farm buildings.

[3] Newbie Castle had been damaged in various sieges and the laird appropriated his relative Robert Johnstone's legacies to use stone intended for a bridge over the River Annan to build a modern extension to the existing old square tower.

It is wrought by water; and is used for grinding wheat and corn and is occupied by Thomas Martin: and is the property of Edward McKenzie Esqr.

[3][9] Sir James Johnstone purchased the Barony of Newbie, but it took twenty-four years of legal action before the last of the relatives of the Corries resigned their titles.

Robert Johnstone of Raecleuch moved into Newbie Castle as the legal tutor or guardian of his heir, the new young laird.

In 1639 the Corries of Kelwood and Newbie resumed legal action against John's widow Bessie and their son George.

[7] Sir John Dalziel of Glennie and others travelled "to the Lord Annandale’s house at Newbie to pay him a visit, beginning with their old pranks, burning their shirts and other linens.

It is said that the servants in the house were amusing themselves with drinking burnt brandy while Lord Annandale was away, and his coach driving suddenly to the door, they thrust the blazing spirits under a bed which caused the conflagration.

The blaze was so great that the chambermaids in Sir John Douglas’s house at Kelhead, three miles distant, could prepare the bedrooms without candles.

The name is written as 'New bay Castle' and Newbay Loch is shown nearby with an outflow running into the River Annan.

[18] No details survive as to the function of the harbour; however, before the bridge was built, an easy crossing of the River Annan would require a boat of some description.
