Creating relationships automatically between accounts that share firstName, lastName, and address

Hi.

Would anyone know of a way to create relationships automatically between records (of the same module, or various modules) that share certain information, such as the person's first and last name, and address?

 

Thanks.

You have to define lookup-fields for the same kind of information (Admin:  https://..../index.php/admin/manageFields) to link them.

As far to my understanding, look-up fields only work with modules. So create a new module that represents the common denominator of the different modules, and add a look-up field to each one of those modules so that they would be linked together through that "common denominator module"?
