Do you have any info on Idas' brothers? I'm looking for Herman F Klahn born in NE and lived in Fort Calhoun. His headstone says he was born in 1888 but the 1920 census says he would have been born in 1886 or 87. I wonder if headstones are sometimes wrong? Everything else I've read fits him in William and Minnies family. Also, their headstone reads as follows: William F Klahn b. Feb 2, 1844, d. Feb 1, 1957 and Wilhelmina K Klahn b. June 28, 1858, d. Sept 27, 1937. They are both buried in the Fort Calhoun Cemetery. There are other Klahns there too. If you would like their names and dates let me know.
