Rosslyn Chapel, a masterpiece of medieval Scottish craftsmanship, holds deep connections to the noble families that shaped Scotland's history—including the Sinclairs and Douglases. One such historic union was the marriage of Henry Sinclair, 2nd Earl of Orkney, and Egidia Douglas in 1404. She was the daughter of Sir William Douglas of Nithsdale and his wife Egidia Stewart, daughter of King Robert II of Scotland and second wife Euphemia de Ross. This marriage was more than just a personal alliance; it merged two powerful dynasties, strengthening ties between the Sinclairs, known for their Orkney holdings and rumoured links to ancient mysteries, and the Douglases, a military powerhouse in medieval Scotland.

Egidia Douglas and Henry Sinclair, the 2nd Earl of Orkney, were married on 17 November 1407. Their union was marked by a significant grant from Archibald, the fourth Earl of Douglas, who bestowed the barony of Herbertshire upon Earl Henry and his Countess, Lady Egidia, and their heirs. This grant was later confirmed by Regent Albany on 20 November 1407.

Egidia Douglas, also known as The Fair Maid of Nithsdale, was the daughter of William Douglas, Lord of Nithsdale, and Egidia Stewart. She and Henry Sinclair had at least one son, William Sinclair, who later became the 3rd Earl of Orkney.

Henry Sinclair, born around 1373, was the son of Henry Sinclair, 1st Earl of Orkney, and Jean Haliburton. He passed away in 1420, while Egidia lived until 1438.  Their marriage was an important alliance between two noble Scottish families, strengthening ties between the Douglas and Sinclair houses.

The Sinclair family had strong ties to Robert the Bruce, particularly during the Wars of Scottish Independence. The Sinclairs were staunch supporters of Bruce's claim to the Scottish throne and played a significant role in his military campaigns. This is recognised by the carving of Bruce's heart, in Rosslyn Chapel.

One of the most notable connections was Sir Henry Sinclair, who fought alongside Bruce at the Battle of Bannockburn in 1314. This decisive victory secured Scotland’s independence and cemented Bruce’s reign as King of Scots. The Sinclair family’s loyalty was rewarded with land grants and noble titles.

Additionally, the Sinclairs were involved in the Knights Templar, and some legends suggest that Sir Henry Sinclair accompanied Sir James Douglas in an attempt to carry Robert the Bruce’s heart to the Holy Land after his death. The heart was ultimately returned to Scotland and buried at Melrose Abbey.

Built later in 1446 by Sir William St Clair, a descendant of Henry and Egidia, Rosslyn Chapel stands as an enduring testament to the Sinclair family's wealth and influence. The chapel is famous for its intricate carvings, some of which depict heraldic symbols connected to Scotland’s noble families. It’s possible that the Douglas-Sinclair armorial was a tribute to this marriage.
