I couldn't find the 1398 burial date, did find 1398 mentioned a couple of times but were basically the same.
Robert Stewart, Duke of Albany (c. 1340 – 3 September 1420) a member of the Scottish royal house, served as regent (at least partially) to three different Scottish monarchs (Robert II, Robert III, and James I). He also held the titles of Earl of Menteith (28 February 1361), Earl of Fife (1361; resigned in 1372), Earl of Buchan (1394; resigned in 1406) and Earl of Atholl (1403, for the duration of Robert III's life only), in addition to his 1398 creation as Duke of Albany.
Perhaps I missed it.
