Oread Butler, of that distinguished family of Charleston, South Carolina, USA, amongst whom are numbered Rhett Butler, married a Scot named John Drummond, the son of a baronet.
John and Oread Drummond's children were:
- William Drummond, grandfather of Bulldog Drummond and Korak
- Colina Drummond, mother of Richard Hannay
- Nyad Drummond, grandmother of Jongor
The Drummonds' grandchildren and great-children were all distinguished persons, having inherited the genetic benefit of the Wold Newton Meteorite's ionizing radiation upon John Drummond's father and mother.
Philip José Farmer describes the extended family in Tarzan Alive, Doc Savage: His Apocalyptic, and a fragment published in Farmerphile #12 as "Jongor in the Wold Newton Universe".
