My ggrandparents might have been from Ukraine, but I'm not sure. Abraham Udes, born 1870, and his wife and oldest daughter all immigrated to the US in New York in 1900. Abraham's naturalization (in 1906) says his home country is Russia. How, on the 1920 census, Ukraine is crossed out and Russia was scribbled in above it. Is it possible they were Ukrainian?
Also, on another record, their surname is listed as "Udec," not "Udes." Do these surnames even sound native? They don't sound Russian, hence my confusion.
