Elizabeth Logan

William Drummond (13 December 1585 – 4 December 1649), called "of Hawthornden". In 1630 Drummond again began to reside permanently at Hawthornden, and in 1632 he married Elizabeth Logan, by whom he had five sons and four daughters.

Partly to please his kinsman the earl of Perth, and partly to satisfy his own curiosity, the poet made researches in the genealogy of the family. This investigation was the real secret of Drummond's interest in Scottish history; and so we find that he now began his History of Scotland during the Reigns of the Five Jameses, a work which did not appear till 1655, and is remarkable only for its good literary style.
