From Old French Jo(h)anne, and so a doublet of Joan. This too was revived as a given name in its own right in the first half of the 20th century. It has to some extent been influenced by the independently formed combination Jo Anne.
English and Scottish: occupational name for a tailor, from Old French tailleur (Late Latin taliator, from taliare ‘to cut’). The surname is extremely common in Britain and Ireland, and its numbers have been swelled by its adoption as an Americanized form of the numerous equivalent European names, most of which are also very common among Ashkenazic Jews, for example Schneider, Szabó, and Portnov.
