The name Toomas Tõnise appears to be a personal name of Estonian origin. It combines the given name Toomas, the Estonian form of the biblical name Thomas, meaning “twin,” with the surname Tõnise, which likely derives from the Estonian given name Tõnis (a variant of Anthony) and the patronymic suffix “‑e,” indicating “son of Tõnis” or “belonging to Tõnis.”
