Obe is of Hebrew origin, meaning 'servant'. It's a diminutive form of the name Obadiah, which also translates to 'servant'. This name has been used sparsely throughout history but gained some traction in the late 19th century.
"The name Obe experienced a brief surge in popularity between 1881 and 1882 with six births each year, followed by a gap until 1915 when seven babies were named Obe. The name saw its peak in the mid-1920s with seven births in 1922 and five or six births annually from 1923 to 1926. After another lengthy gap, there was a single birth named Obe in 1948."
