I found these photos in my deceased grandmother's photo album. I am not sure of who she knew in the photo.
A little history on her family. Her mother and father both immigrated to the US from Zuromin Poland in the early 1890s before they were married. Most of their immediate family immigrated as well. Zuromin was in the Russian partition of Poland of that time, but these photos don't look Russian to me. Her grandfather never immigrated, and was a Captain in the military, presumably the Russian army. (I have posted his photos in the Imperial Russian/PreWWI part if this forum).
Perhaps this was of a cousin or friend of the family.
Can anyone provide any light on these photos? I am estimating them to be of WWI era, but I am not sure. The helmets look Prussian/German to me.
