Thanks for the context. I don't remember the details of the discussion I read, so I'll take the doubts with a grain of salt then.

There was a DNA test a few years later (one of Stalin’s grandsons by Vasily volunteered) which corroborated Montefiorre’s story.

I saw this too, in the Siberian Times, but when I shared it comrades told me it wasn't a reputable newspaper. Could have just been cope, idk.

Edit: I think this may have been what I saw. I'm reading it now.
