What is the meaning of the name Onny ?

Onny is Finnish in Origin.

Onny is a rare given name with several plausible roots. Most prominently, it aligns with Finnish Onni, a longstanding top 100 boy's name meaning "happiness; good fortune," from the Finnish noun onni; Onny functions as an Anglicized or stylistic spelling. In Britain, Onny also evokes the River Onny in Shropshire, a Brythonic/Welsh toponym likely derived from Welsh onnen "ash tree," giving the name a subtle nature connection. As a nickname, Onny appears in 19th- and 20th-century parish registers and censuses for bearers of Onora/Honora and occasionally Onesimus, later standing alone.

Usage today is uncommon but cross-cultural and largely unisex. Variant forms and near-equivalents include Onni, Oni, Onnie, and Oney; related names are Onora and Honora. Depending on the lineage chosen, meanings span "happiness, luck," "ash tree," and "honor." Pronunciation is typically ON-ee. Compact and international, Onny suits modern naming styles.
