Here is pretty good reference found on Volga Germans society website. Scroll down to 1921-1922 section because the website starts with 1891-1892 Volga famine during czarist times. You'll find there a few articles on Volga Famine by the Western Reporters who were allowed in. There is also one on the Ukrainian Famine of 1932-1933.

Here is the eyewitness report by Gareth Jones on collectivization in USSR in early 1930's, including Ukrainian Famine. He lumps Ukraine and Russia together when he mentions Russian peasantry, but he was witnessing the Famine in both Ukraine and Russia.

I am not surprised that the Russian priests and the newspaper reporters and the college professor call Ukraine Russia.
We have been fighting this for years just as when we hear about all the "Russian" deaths of WWII.
It was Ukrainians that took the big hit - and we are also reminded that 500,000 germans perished (who had lived there since Czarist times)
