Irish Constitution Lodge Warrant No. 669 first met in Dungiven, Co. Londonderry, from 1787 until 1856, then reissued on the 23rd April 1938.

In 1880 George Smith Clark then aged 19, was a founding partner in the Belfast shipbuilders Workman, Clark & Co Ltd., known locally as "The Wee Yard". It expanded rapidly to employ 3,500 men in 1895, and 9,000 in 1909. In 1902, and 1909 its tonnage produced was the highest of all UK yards.
The new shipyard had already taken the repair and new construction contract for J.P. Corry & Company, and was the first shipbuilder to produce refrigerated ships for carrying beef and fruit. After the First World War it enjoyed mixed fortunes, and closed in 1935.
Both partners had served their time as premium apprentices at Harland and Wolff the largest shipbuilder in Belfast, and graduated to junior management positions.

Bro. Albert Brand contemplated the forming of Sir George Clark Memorial Lodge for the benefit of those brethren who were night workers, and were unable to attend their Mother Lodges, many of whom worked in the newspaper printing industry. With the assistance of W. Bro.Thomas McClure, W. Bro. Joseph McAdam, and Bros. Arthur Patterson, and Henry Harrison, all of whom were enthusiastic members of the craft, at the first meeting, which was held at 28 Gainsborough Drive, the home of Bro. Henry Harrison, it was decided to approach Sir George Clark, 2nd Baronet for permission to name the Lodge after his father (of renowned shipbuilding fame) who was a keen Freemason.
They received permission, and called a meeting in Alexandra Park Avenue School, Belfast, which all 25 foundation members of Sir George Clark Memorial Lodge attended.
The Lodge was dedicated on the 23rd of April, 1938 at 5 o'clock, by the R. W. Bro. John W.Gilmour, Deputy Grand Master of the Province of Antrim
