I have a spreadsheet column which stores client names in the format 'Mr & Mrs
Fred Bloggs' or Mr Iain Kerr.

I want to be able to sort this in alphabetic order based on the Surname
only. Is there a multi function to determine where the first space charactor
is from the Right Hand Side? This would give the the start position (-1) of
the Surname.

I figured that if I can isolate that into a hidden column, then I can easily
sort on it.
