This may be the wrong place for this thread, but I can't find a better match.
This is my wife's great uncle from a family photograph taken in Shargorod, Vinnitsa, Ukraine around 1900. The family was Jewish. By 1905 he has immigrated to the US, under the name David Corn.
Can anyone identify the uniform? The rank?
Is there any possibility of researching this soldier's military record?
