Thanks Florian
I've had a look at the profiles in this category and as you said, they are early medieval profiles at the time when Bavaria/Bayern was ruled by men from many different families or dynasties. Consequently there is no easy fix of moving most of them to a particular "House of ..." category.
Also I personally feel that the main priority for many of these medieval/pre-1500 profiles is still to make sure they are sourced with reliable sources, and connections between profiles are based on sound research rather than adding 'House of ..." or 'Rulers of ...' categories.
My suggestion would be that the Konigreich Bayern category is deleted from these profiles and when people have time to undertake some in-depth work on them would be the time to consider what categories could or should be added.
