contact details

I have a database which has contact column eg. Mr Peter Smith

I am writing a new database which is to have three seperate columns.. saluation, first name and surname. What would be the best way to split the column up?? I was thinking on concentrating on the spaces??

Note: some conacts may not have saluation inc in the contact column, and in this case the saluation column should be blank...

That bit should make it interesting.
Do you have a list somewhere of "valid" salutations?
What will you do with the extra space in:
Mr Peter Smith Jr.
