Thank you for contacting me. I am quite sure this reference is to my grandfather, Anton Eichler. He did come to the USA by way of entering in Canada. I know very little about his arrival or his locations in Canada prior to arriving at his destination in Chicago, Illinois to join his wife and children. I would appreciate any more information (or insight) that might help me obtain for facts. Where in northern Bohemia is Wistershen? Do you think your grandfather was a friend of Anton Eichler or do you suspect they may be related? The photo of Ludwig certainly could pass as a relative to the Eichler family.
