Mike Moran, any help with the Thurwangers in St. Mary's Cemetary is more than welcome..I live much further away than three hours..try Pennsylvania. I am pretty certain that there are Thurwangers in the newer cemetary..That is probably where my great grandmother , Rose Thurwanger is buried,,she died in 1955. Not familar with any Thurwangers that have married Egert.so will be interested to hear who..As far as I know there were two families in Kewanee..Jacob Thurwanger and wife, Rose..and John Thurwanger who was a cousin of Jacob's and his wife ,Lizzie who was a sister to Rose. Thanks, Marg
