These don't have to match.
When for example an assistant is mentioned, I added that type of person behind the "name" within braces and the name of that person under "surname" and "first name".
In the case of "Maxwell, Isabel", these names are listed for certain phone numbers without mentioning who that actually is.
I will remove titles after each page start when I'm done. Right now that helps me for entering and checking data. Should be simple to filter out anyway.
