Well Howard C Heintzman was my great uncle. Brother of my Grandfather. he worked for Heintzman and Co. I have a box of material that has some information and I can put you in touch with his grand daughter if you like who I'm sure has lots of Information. I'm not sure who George Creiton Heintzman is. I know George Charles who was my great grandfather and have quite a bit of information about him I also know George Crossley Heintzman who is my father and obvious know quite a bit about him. If you let me know what you are looking for I might be able to help.
