Well I do this often when I have certain covers.If the countries concerned are not to complicated in terms of googling through different data sources.Generaly speaking most of the covers existant today were preserved over years and years,and they could be known people or companies that to this day ;for some; continue in one form or another.Plus there is some history behind every letter:small, but interesting enough to dig into.It's like being a detective of sorts!
The real challenge is deciphering a cover in every angle of light as you do also.
((The text essentially says it is accorded to Mr.Henri wolff attorney in
Diekirch is dispensed from the training course(something of that nature;law terms) required in the exercise of his official status as attorney)) the official decrees and the obtention of his new status..
In fact there is still the family Wolff in luxembourg.
Another thing ;if you can find covers with the same name often,that means it was someone very active in the society.Company directors,Merchants,Traders import export and the like and they can span 5-20 years of mail reception to their same addresse... I'm talking about the 1845-1890 time zone in general.
