Appelman graffiti Wondering if it was possible to find out who wrote this, I showed this photo to a couple of Rotterdam-based Appelmans. No luck so far. Bob Appelman wrote on 2006/11/17: My ancestors departed from Rotterdam on their way to America. This was specifically John Appelman, son of Gustaphus Appelman from Wolgost. I'd love to connect with any of these "cousins"
