One member of the Hessen-Nassau family settled far, far away: Rudolph Huthsteiner.
Rudolph became the most traveled guy in this genealogy – at least for the time around 1870. At this time travelling to Australia took 3-4 weeks at least. On the Sea !
Likely he left Germany (Prussia) due to suppression of free ideas, as already his brother Wilhelm was demoted due to liberal acting as censor and police commissioner in Barmen. Probably he also had contact to Friedrich Engels as his brother did.
