I am cleaning up a large address Access database for a spanish law firm. The
first and last name fields are tricky because often individuals have four or
five names and often they are placed inconsistently in the first and last
name fields. We are going to convert the database into an Excel file to
accelarate clean-up, but we are having a tough time removing duplicates
because of the naming issues. Any ideas on how to do this? Here is an
example of the problem:

First Last
Jose Maria Ramon Luis Olivida
Jose Maria Ramon Luis
Jose Ramon Luis Olvida

All three of these rows list the same person, but I don´t know how to fix it
other than manually. Note that this is a database with 20,000+ rows.
