Notes for Sefroy Iott: As with so many names, I have found this spelling to vary. In a satement that was written by Frank F. Aplan, we see that Cefroy is also Sefroy and Iott can be seen as Jott or Iyott. The 1860 census of St. Charles, Missouri it appears to be Cefroy. The Index to the St. Charles County Missouri Baptisms 1792-1852 uses two spellings - Gisisfroit H. and Sifroid H. Hiot. So far I have found that he had three wives. #1 is Elionette Janis, #2 is Ellen, an Indian wife in the Platte Country by 1857, and #3 is Mary, another Indian wife by 1860 (or had it been one wife with the name Mary Ellen?). He had been an interpreter between the whites and the Sioux Indians. His Indian name was "Stand In the Prairie."
