Juliana Campbell was the daughter of Sir Hugh Campbell of Loudon and his first wife, Margaret Gordon. She was betrothed to her kinsman, Colin Campbell of Glenorchy, when she was thirteen and he was seventeen. The following year, Colin settled the lands of Loch Tay on his bride. In 1631 his father died and he became Laird of Glenorchy. Possibly at Lady Campbell's urging, he then spent 3000 merks on new furnishings for his castles at Balloch and Finlarig. An inventory taken when he died records fine silk bedhangings embroidered with the names and arms of both Sir Colin and his wife. Lady Campbell, fifty-two in this portrait, is depicted as a forceful looking lady wearing an elegant pearl headdress with a highly fashionable gown and carrying a feather fan.
