Who Are They? 52 Ancestors in 52 Weeks: Week 9

As I have mentioned before everyone should know the importance of lightly writing on the back of old photos as to who the individual/s are. If writing on the reverse of the photo is not an option, some means of name identification should be accomplished. I have numerous photos of relatives and ancestors that date back to the 1860s and maybe earlier. Unfortunately everyone who would be in the know as to who these people are are long gone; some upwards of one hundred years or more.

This week's ancestor biography is on ... I do not know?  Below are photos of unknown ancestors. I have an idea of who they might be but that is it. No solid proof. Only a hunch?

Below are two photos that came from the town of Zierikzee in the Netherlands. Zierikzee is the town where my great great grandfather Hendrik Koreman and his three siblings were born.  Around 1852 the family immigrated to America. On the reverse side of the photos is the address of the photographer, which is how we know the photos are from the Netherlands. The below photos could be of siblings to my ggg grandfather Cornelis Koreman. Whoever they are? They felt it important to send these photos to New York.

The remaining two photos below are from Rondout, New York; just outside Kingston. My grandfather told me numerous times about his ancestors living in Rondout before coming to Albany. These photos are proof that they were in Rondout.

The final photo, I do not know if it can be called a photo. It is like a piece of glass with a negative print in it.  It is very difficult to see the print. However if a dark background is placed behind it then the image becomes very clear. I do not know what type of photo it is. If anyone knows the answer to this question, please let me know. One noticeable thing is the man in this photo is also the same man in the photo two pictures above. Both of these photos came from different cousins within the Koreman family.
