I was hoping to limit my study geographically to just Australia/New Zealand & Switzerland for the moment. That is quite a handful when you add in marriage partners and their parents.
There are Iseppis in Italy, France, England, north Africa, North America, South America, Austria, Germany and Ukraine that I’ve seen so far.
If the requirement is to be broad for “One Name Study”, then I’ll accept it. I was hoping to limit it so I didn’t get overwhelmed.
