Ottilie von Faber said,
By marrying Alexander Grafzu Castell-Rüdenhausen, 6th Earl of Castell-Rüdenhausen,
Count Alexander led the company.
Rotar von Faber said that when the heir of the company got married,
Declared that the name Faber should be retained.

Not Castel-Ludenhausen, with royal approval.
Faber-Castell,
In other words, I have the current company name.
