Siri works with custom labels for related contacts, so you can ask it to "Call my bank" or "Send a text to my fianceé".
To set this up, simply tell Siri that "X is my Y".
Or you can edit your own contact card, add the "Related People" field if it's not already there, and then use custom labels when linking contacts.
