He was the son of Edward Devereux, 11th Viscount Hereford and his wife Catherine Mytton (d. 1748).

Lord Hereford married Henrietta‌‌‌‌ ‌‌‌‌Charlotte‌‌‌‌ Tracy (d. 1817), the daughter of Susan and Anthony Keck. Henrietta was born Henrietta Charlotte Keck, but changed her surname to Tracy in 1774 — before her marriage — as a condition of inheriting her uncle Robert Tracy's estate. Edward and Henrietta had no children and the Viscountcy was inherited by Edward's younger brother George Devereux.
