The original installer *should* have labelled the downstream outlets
protected by the GFI with a label that says as much. Then you'd know
(a) not to install a GFI at this location, and
(b) if the outlet is off, you need to search for a GFI somewhere else.
But not labelling them seems typical. My house has one GFI on the
outside wall that feeds (and protects) two other outdoor outlets, both
unlabelled. There's a GFI in the tiny ensuite bathroom off the bedroom
that also protects outlets in the main bathroom and the downstairs
bathroom, again without labels.
