Meaning and history
Siana is used in Welsh as a feminine name related to Siân, the Welsh form of Jane. Jane ultimately derives from Hebrew Yehochanan, meaning “Yahweh is gracious.” The expanded ending may be affectionate or stylistic. The same spelling also appears in other cultures, where it can have an independent origin, so the Welsh explanation is not universal. Siân is well established in Wales, while reliable prominent bearers using the exact expanded spelling Siana are comparatively limited.
