will work to have a VerifiedPatient table and a PatientAlias table
and cut and paste common code, properties, etc. between the
classes, but that's not very DRY (don't repeat yourself) and OO,
but it may have to do.
You don't have to use inheritance to not repeat yourself. You may
work with composition.
You have a couple of entities:
PatientAlias <<---> VerifiedPatient
and
PatientData to which you may have relationships to both of the
patient entities.
