The Tennyson boys? (6)
I believe the answer is:
alfred
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for alfred that I've seen before include "King of Wessex, known as "the Great"" , "King after Ethelred" , "Saxon king" , "... the Great, 9th-century Anglo-Saxon king" , "Cake-burning king" .)
