I just checked BLM.GLO [Bureau of Land Management, Government Land Office].There are only a few listings for ZEIMET.Interestingly, the patent for one was to John and Mary, 12 N 1913, Doc. 08549, Accession 364861, Custer Co., SD, in Sections 11, 12, 13, & 14, T 5S, R 4E, Black Hills Meridian.That is the only one I've seen that included what looks like a wife on the title.Nearby were Michael ZEIMET & Peter ZEIMET.Michael was in Custer Co., T. 6S, R 4E, BH, in Sec. 2.Peter was also there and in Secs. 3 & 10.Both of these were in 1910 & 1921.
Nicolas was of Brown Co., MN, T 110N, R 31W, 5 PM, in Sec. 31, in 1868.
Richard Paul ZEIMET was in Riverside Co., CA, in Sec. 32, T 4W, R 8E, San Bernardino Meridian, 1959, small tract.For more details, check out the site.
