“Another German nobleman settled in the beginning of the 19th century in Peru: Clemens Anton Freiherr von Althaus. He was the illegitimate son of the countess regent of Schaumburg-Lippe and Clement August von Kaas. He was first an officer in the army of the kingdom of Hanover and moved to Peru in 1820. In Arequipa he married in 1826 a cousin of the writer Flora Tristan. Their descendants still live in Peru.”
