The Bünau family's website states that by a "private ordinance" the family had obliged its men to use only the forenames Günther, Heinrich, and Rudolph, which is why within this very extended family there are numerous men with the name "Heinrich von Bünau". This has often led to confusion between them in previous research: for example, in the history of the Saxon state, Heinrich, Count of Bünau, has often been confused with his father of the same name, who was Chancellor at the Court of Dresden.
