Barbary surname

[Gorse]

Hi All, does anyone know anything about the surname Barbary? Its not very common in the whole of the UK but has some connection to Cornwall and is certainly where it is most commonly found in the UK. I'm trying to find out its origins and how it ended up in Cornwall and where it came from as I don't think it is originally Cornish. So any help, information, points in the right direction or light shone on this is really greatly appreciated.

Kind thanks

ps apologies for double posting as I posted this in the general Cornwall Questions section before I noticed this section.
