Gastonnia

Gastonnia is a rare and somewhat unusual name, appearing to be a feminized and Latinized form of 'Gaston'. The name Gaston itself is of Germanic origin, derived from the element 'gast' meaning 'stranger' or 'guest', or alternatively, referring to the region of Gascony in southwestern France. The addition of the '-ia' suffix is a common way to feminize names or create place-based names, giving Gastonnia the sense of 'belonging to Gaston' or 'from Gascony'.

Its usage is extremely limited, suggesting it may be a modern coinage or a very localized historical name. It does not appear in standard etymological dictionaries of names, indicating its rarity. It might have been created by parents looking for a unique name with a French flair, or perhaps as a tribute to a male relative named Gaston.
