Serena Blakeney was a daughter of Sir Percy Blakeney and Alice Clarke Raffles mentioned in Tarzan Alive by Philip José Farmer. She married the 12th Baron Tennington; their children were:
- The man whom Trader Horn called George T—
- Edward Rutherford, 13th Baron Tennington, grandfather of Tarzan
- John Rutherford, father of Professor Challenger
- Venetia Rutherford, mother of Ludwig Horace Holly and grandmother of Bulldog Drummond and Korak
- Violet Rutherford, the mother of Sherlock Holmes in Farmer's mythos
- Lucasta Rutherford, grandmother of Lord Peter Wimsey
Lord and Lady Tennington can thus be considered key to Farmer's Wold Newton Family.
