I replied privately to the enquirer who posted the message but for everyone'S info:-
Definitely Ukrainian. You can see that by their use of Roman i in certain instances not Cyrillic for i Ukrainian is probably the closest lang to Russian out of all the Slavonic langs. Any Russian speaker should be able to it do it for you.
Re pdf docs - in 2008 there used to be a computer prog called abbyfine or similar that converted pdf to word doc. Check on google search as the world has moved on a lot since then.
NB: Google just offered me the option to translate and hey presto it worked on the main page. When I clicked on the link to the first record it brought up a pdf. When I looked briefly at the pdf, it seemed to me as if the language is pre-revolutionary Russian, not Ukrainian. They changed spelling rules after 1917. The more I scroll down it looks like Russian and very clear handwriting, unlike some docs.
