Who is the direct living descendant of Robert the Bruce?

Answer 1

The direct living descendant of Robert the Bruce is the current head of the House of Stuart, namely the 21st Earl of Elgin, who is known as the Honorable Simon Fraser. He is a direct descendant through the line of Robert the Bruce's daughter, Marjorie Bruce, who married Walter Stewart, the 6th High Steward of Scotland. This lineage connects back to the royal line of Scotland, stemming from Bruce's reign in the early 14th century.
