Jansen

The Jensen variant is the second most common surname in Denmark. All these names are derived from the Hebrew name Yochanan, which literally means "Jehovah has favored," which was Latinized as Johannes, gained tremendous popularity during the medieval era. This is due to the exploits of St. John the Baptist, St. John the Evangelist, and nearly one thousand other saints of the same name. The suffix -son and its variants are translatable as 'son of.'
