[Ger-Poland-Volhynia] Germans drafted in Russian army

[Jane Wilkens]

My great grandfather emigrated from Volhynia in about 1896, taking a  
ship in May of that year.  I'm not 100% sure where he was living but  
my grandmother was born in the village of Michailoska in Kreiz  
Zhitomir in 1894.  According to family stories, he was about to be  
drafted into an army and so left for America to escape this draft.   
I'm curious if Germans were subject to a draft (and what army?) while  
living in Volhynia around that time.  Anyone know?
