[rekem]

Here is the latest information:
and there are no arms !

Genealogisches Handbuch des Adels 131,483

The exact day is missing
and the question remains : "where is Torby ?"

The only thing I could find is that Torby is a town in Finland. Merenberg was a title without a territory; perhaps Torby was as well?

And this:

According to Russian Wikipedia, Sophia Merengerg was made Countess Torby in 1892 by the Duke of Nassau. The title was invented by GD Mikhail Mikhailovich himself in memory of the village Tori in Georgia, which was part of GD Mikhail Nikolayevich's Borjomi estate.
