# How we do it
#
#  [1] The name is split into white-space seperated parts
#  [2] If there is only one part, it becomes the firstname
#  [3] If there are only two parts, they become first name and surname
#  [4] For three or more parts, the first part is the first name and the last
#      part is the surname.  Then while the last part of the remainder starts with
#      a lower case letter or is in the list below, it is prepended to the surname.
#      Whatever is left becomes the middle name.
