I am new at genealogy and my ultimate goal is to see if there are living
descendants in Russia. My grandparents came here in 1905, according to the
1920 US Census.

Toi be more accurate, your grandparents came to the US in 1905, according to
what they told the enumerator in the 1920 US census. That may or may not be
the same thing. In the case of my own grandfather, it isn't, for example.
