Variant of Otway, from Old English elements meaning prosperity and war.
Ottaway is a variant of Otway, from Old English elements associated with prosperity and war. That pairing of abundance and battle gives the name a classical, almost heroic feel.
As a surname-style given name, it carries the kind of weight that often makes old family names feel especially substantial when revived. The name sounds stately and a little formal, with a rhythm that suggests heritage. Ottaway has the charm of something historic without being overly common, which makes it feel dignified and distinctive.
Because it comes through surname tradition, it can also feel grounded in place and lineage. The overall effect is old-fashioned in the best way: confident, rooted, and quietly imposing.
