Euphemia Elphinstone (also written Euphame or Eupheme; born 11 May 1509) was a mistress of James V of Scotland and the mother of his son Robert Stewart, 1st Earl of Orkney, born in 1532,[1] as well as another child who died in childhood.
She was the second daughter of Alexander Elphinstone, 1st Lord Elphinstone and Elizabeth Barlow or Barlay (c. 1476 – 10 September 1518), an English woman of the household of Margaret Tudor.
Her brother Alexander, Lord Elphinstone, died at Edinburgh following the Battle of Pinkie Cleugh.
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.
According to legend, many people in the Shetland Islands are descended from her; in particular, those named Bruce are supposed to be descended from her children by John Bruce.
