On Young Man of Arévalo, whose {{Infobox writer}} has the line | death_date = uncertain, possibly second half of 16th century{{sfn|Thomas|Chesworth|2014|p=159}}. I presume this is where the 2014 death date was gathered from. If so, this can easily be made into an exclusion, either by excluding years in {{sfn}} or other templates, or excluding "uncertain" in death_date/birth_date parameters.
