The name Tennyson is a boy's name of English origin meaning "son of Dennis". Tennyson and is often added to lists like Literary Baby Names and discussed in our forums with posts like "A Name That Would...".
From the experts:
Few people would have considered the surname of this famous Victorian poet as a first name until Russell Crowe chose it for his son in 2006. But, as a rhythmic three-syllable patronymic, Tennyson has a lot going for it, not least of all the appealing nickname Tenny; it would make a novel choice for the son of a Dennis.
Other options: The poet's first name, Alfred, or the name of another esteemed bard, such as Eliot, Poe, Byron, Lowell or Lorca.
