Here's an interesting account of the Heinrich LXXII:
"Heinrich was now Lord and Master of a principality of 165 quare miles of wooded hils & modest farmland harbouring about 20,000 inhabitants. His capital was Ebersdorf on the Saale, a town of about 1,200 whewre he spent most of his time hunting, inspecting his woodlands and begetting [illegitimate children]. Serenissimus, as he was styled did have partial control of the bustling town of Gera, which had more than 10,000 inhabitants but he shared sovreignty there with his cousin, the Prince of Reuss-Schleitz, who was also named Heinrich [surprise, surprise!].
...Heinrich LXXII's father had been...Heinrich LI; twenty other male Reusses had been born between the father's birth & his son's.
The prince did not receive many visitors who were not named Heinrich...
[Lola Montez - future-lover of Ludwig of Bavaria - whom he
was entertaining] was pleasantly surprised by the court of Ebersdorf, finding even its modest charms more than she had expected....but the sameness of each day soon bored her. She found [Heinrich] morethan a bit ridiculous in his vanities and she was frustrated that none at the tiny court could hear her jokes about him without being shocked."
