From contribution rules:
"To determine whether to enter the name directly as credited, or to use the "Credited As" field, use the Credit Lookup tool.

It is not necessary to document the source of the common name, outside the use of the CLT. If there is a dispute over whether the credit references the same person, documentation may be necessary. However, in most cases, it is not required.

The inclusion of CLT results in contribution notes is strongly desired but not required. Note: In the case of uncertainty, leaving this out may cause the contribution to be declined."

You can make a thread to establish the common name and verify all the credits in the database; the variant most used in the credits is the common name.
