The following article contains an answer for the question: What is the first name of the person who it was probably during his tenure at the SOW that the supporting buttresses to the choir and transept walls were built? , can you please find it? 

Since the abolition of bishops within the Scottish Church in 1689, ownership of the abandoned cathedral fell to the crown, but no attempt to halt the decline of the building took place. Acknowledging the necessity to stabilise the structure, the Elgin Town Council initiated the reconstruction of the perimeter wall in 1809 and cleared debris from the surrounding area in about 1815. The Lord Provost of Elgin petitioned the King's Remembrancer for assistance to build a new roof for the chapterhouse and in 1824, £121 was provided to the architect Robert Reid for its construction. Reid was significant in the development of a conservation policy for historical buildings in Scotland and was to become the first Head of the Scottish Office of Works (SOW) in 1827. It was probably during his tenure at the SOW that the supporting buttresses to the choir and transept walls were built.In 1824 John Shanks, an Elgin shoemaker and an important figure in the conservation of the cathedral, started his work. Sponsored by local gentleman Isaac Forsyth, Shanks cleared the grounds of centuries of rubbish dumping and rubble. Shanks was officially appointed the site's Keeper and Watchman in 1826. Although his work was highly valued at the time and brought the cathedral back into public focus, his unscientific clearance work may have resulted in much valuable evidence of the cathedral's history being lost. He died on 14 April 1841, aged 82. A fortnight later, the Inverness Courier published a commemorative piece on Shanks, calling him the "beadle or cicerone of Elgin Cathedral", and writing:
Some minor works took place during the remainder of the 19th century and continued into the early 20th century. During the 1930s further maintenance work followed that included a new roof to protect the vaulted ceiling of the south choir aisle. From 1960 onwards the crumbling sandstone blocks were replaced and new windows were fitted in the chapterhouse, which was re-roofed to preserve its vaulted ceiling. From 1988 to 2000, the two western towers...
