This category contains pages transcluding Template:Infobox family (talk) with unknown parameters (undefined, misspelled, etc.).

Pages are typically sorted alphabetically by the unknown parameter that is used, e.g. pages using unknown parameter |foo= will be sorted under "F". The name of the page is typically used as a secondary sort key.

Unknown parameters can be detected using Module:Check for unknown parameters in the template. To show the information listed here on a category page, use {{Unknown parameters category}} on the category page.
