The document which that small image comes from was all very clearly written, except for that one name which I guess is "
Joannes."
It is difficult to say whether it was a Cyrillic alphabet or a Polish variant of a Latin alphabet "they" first learned. They all seem to come from two or three countries at the same time.
I am more of an American than a Russian, so a Russian's Latin letters would appear strange to me. There is an other difficult name that I forgot all about. I will post it soon.
