Background
She was the second daughter of Alexander Elphinstone (born c 1480, died 9 September 1513, at the Battle of Flodden), created Lord Elphinstone in 1510, and Elizabeth Barlow (Berclay) of Aberdeenshire (c 1476 – 10 September 1518).
She was the second daughter of Alexander Elphinstone (born c 1480, died 9 September 1513, at the Battle of Flodden), created Lord Elphinstone in 1510, and Elizabeth Barlow (Berclay) of Aberdeenshire (c 1476 – 10 September 1518).
The family hailed from Elphinstone in Stirling. Her brother Alexander, Lord Elphinstone, died at Edinburgh following the Battle of Pinkie Cleugh, and is the ancestor of the Elphinstone family. Euphemia married John Bruce of Cultmalindie (c 1507 – March 1546/7), a descendant of Robert the Bruce, and had five children: Laurence Bruce, Robert Bruce (born c 1536), Henry Bruce (born c 1538), James Bruce (born c 1540) and Euphamie Bruce (born c 1542).
She died either in 1542, or after 1547: there is no firm evidence for any death date.
Her two most significant children, Laurence Bruce and Robert Stewart and their families were to become closely entwined in the Shetland Islands, of which Laurence Bruce was appointed Sheriff by his half-brother.
