Thank you, Shlomo. This looks like terrific work, and I'm grateful to have this new information.

Your second link seems as if it may be broken, however. When I click on http://shl2gur.tripod.com/Mogilevgub ernia/Mogilevgub.htm  I get taken to an error message.

Good luck, and it's generous of you to share such substantial work with all of us.
