I'm married to a girl who's name is VERHEES. Her father's name was VERHEES and his mother was called ANNA EXNER. (She is my wife's grandmother) My wife was told that her grandmother came from Polen (Poland ?) and her father was serving the army of a Tsaar in Russia. He deserted and lived in a castle in Polen (poland ?). Do you know where that castle is situated in polen, because we are visiting Poland this summer and want to visit that castle. Have you more information of other Exner's in Europe ? Thank you very much.Peter and Anke.
