I am looking for the birth and death years of Russian composer
Feodosiy Rubtsov.  He arranged a traditional Russian song called
Veniki (Brooms), and the publisher Musica Russica lists him as F.
Rubtsov.  Many alternate spellings exist such as Rubcow Feodosij
Antonowitch, and it seems as though he was born in 1904.  I need
confirmation and the death year.

This quote from a 1998 source gives his birth year as 1904, but gives
no year of death. This implies that he was still alive in 1998, but of
course it tells us nothing about whether he is still with us:

"In 1937 two Soviet composers wrote the first concerti for accordion.
Feodosy Antonovich Rubtsov (b. 1904) of Leningrad wrote Concerto No. 1
for Bayan (a Russian button-accordion) and Russian Folk Instruments
Orchestra, which was the first large-scale piece of art music in the
history of the Russian accordion."
