Look at that beard! I looked it up. It’s not quite an Old Dutchman, funnily enough. This is a style of facial hair often called a Chin Curtain or The Lincoln. I’m going with Chin Curtain, since the one thing I do know about this photo is that it was taken in the Netherlands, not America.
Anyways, this photo was in with others of the Kool family in the possession of Halbo Kool (the living one, not any of the previous generations). He doesn’t know who it’s of, but we are able to tell it was taken in Groningen and you can see a slight resemblance to Cornelis Kool  in the eyes, nose and lips. His clothing is similar to that of ancestors in other photos I’ve estimated to be from the mid- to late-1800s. All this leads me to guess that the ancestor in the photo is likely one of Cornelis Kool’s brothers, of which he had three: Jan Kool , Heero Kool  or Harm Kool . There was a fourth brother, but he did not live to adulthood.
