From the Roman family name Flavius, related to Latin 'flavus' ('golden-yellow, blond'). This is golden as hair/colour ('probably originally yellow-haired') rather than gold the metal — distinct from the 'aurum' names.
From Latin unda 'wave'. Popularised by the water-nymph heroine of Friedrich de la Motte Fouque's 1811 novella Undine; the undines are elemental water spirits.
Flavia and Undine are given to a similar number of US babies today.
Flavia means golden, yellow-haired (latin origin), while Undine means Of the waves (latin origin).
In US records, Flavia first appears in 0 and Undine in 0, so Flavia has the longer recorded history.
