I'm not sure how this will work. Please check my web pages and see if any of your family is pictured

Issac Baerg is the third man to the right, back row. This was part of a larger picture of some kind of gathering. Anyone know where it was taken?

Picture 6 looks like the same man a picture 3. It looks like a Russian army uniform.
Some of the Nikkel or Martens family did serve.
The woman in #5 is the same person as the girl next to Isaac Baerg in grp1.jpg photo 12.

Photo #7, the man looks like a Baerg
#8, the man on the far right looks like a Nikkel
The young man in #12 is Isaac Baerg born 1866. The girl does not seem to fit the age of any of his sisters. She is shown in a wedding photo in #5
