Johis Langman is the first of the family to appear in Cornwall and in
England. He is believed to be a German merchant who arrived from
Luebeck during the period of blooming of the German Hansa trade
organization. The Hansa did extensive trade with Britain during this
period and even had offices and warehouses in London.
Perhaps Johis Langman is identical with the John Langman who was
married to Elizabeth and died in 1605 leaving son John Langman of
Lesnewth (who married Wilmot Painter on 5 June 1573.
In England the family is mentioned as Langman, Langaman and Langamann.
(Compare the German Langmann, Lanckmann and Langermann).
