Jón is a common male name in Iceland, derived from the Hebrew name Yohanan, meaning "God is gracious." It is widely used in various cultures, often appearing in different forms, such as John in English and Juan in Spanish. In Iceland, Jón is often combined with a patronymic or matronymic surname, reflecting the father's or mother's first name. For example, the son of a man named Jón would have the surname Jónsson, while the daughter would be Jónsdóttir. This naming convention is a significant aspect of Icelandic culture and identity.
