Ianto

Ianto is a Welsh masculine name functioning as a diminutive of Ifan, itself the Welsh form of John, which derives from the Hebrew Yohanan meaning God is gracious. The pet-form suffix gives it an affectionate, familiar character typical of Welsh naming conventions, similar to how Sion and Evan also serve as Welsh adaptations of the same Latin and Greek transmission of the Hebrew original. The name gained broader international recognition through the Welsh-language television series Torchwood, where Ianto Jones was a central character. Ifan and Evan are among its closest cognates within the same naming family.
