"Brad Edwards" and "Bradley Edwards" might be the same individual.
Yes, the dataset also has three entries for Virginia Giuffre, "Virginia L. Giuffre", "Virginia Roberts Giuffre", and "Jane Doe Number 3 (Virginia Roberts)"

I’m sure some developer/archivist is working on a name authority as we speak.
