Octavius m
English: from the Roman family name, derived from Latin octÄvus eighth. The name was fairly frequently given to a male eighth child (or eighth son) in large Victorian families. It is much less common these days, when families rarely extend to eight children, but is occasionally selected for reasons of family tradition or for some other reason without regard to its original meaning.
Cognate: Italian: Ottavio.
