How do you find out where the 'Home Province' for a Commander is?

For a regular unit, that info is displayed at the top of their stat/info screen, but for a Commander that same info isn't displayed. Is it hiding somewhere else which I haven't noticed, or is it just not available?

Reason I ask is that in a game I'm playing I've got a wandering site searching Naiad which I summoned, but I can't remember where I summoned her to send her home to recover.
