Just a minor issue: Bořivoj I.'s Current Last Name is given as "z Czechy". While old Czech orthography did render the modern "Č" as "Cz" most other spelling in medieval Czech profiles (including his First Name) uses modern orthography. Therefore, for consistency's sake should this CLN be changed to "z Čechy"? Or would anybody want to change his First Name to "Borziwog"?
Addendum: If this change is agreeable should it then be applied to the CLN for other Přemyslovci?
