Shouldn't it be the other way around? i.e.
Unsourced Profiles, Stermenszky Name Study
rather than Stermenszky Name Study, Unsourced Profiles
otherwise all the subcategories will end up under 'S':
Stermenszky Name Study, Unsourced Profiles
Stermenszky Name Study, Hungarian Profiles
Stermenszky Name Study, English Profiles
Stermenszky Name Study, Prussian Profiles
