Hi, my name is Bill Knight and I live in Washington state. I saw your post on Ancestry.com about Cocanowers and followed the trail to your web site and saw that one of the lines you were interested in was Knights in MO and KS. I don't know if mine is the line you're looking for but I'll tell you what I know and you can judge for yourself.
My great-grandfather is William Asby Knight. In 1881 he married Parthena Jane Cocanower (aka Jennie or Eliza Jane). They had four children: Edith Loren Knight b. 26 Jan 1883 in Illinois, Perry Francis Knight b. 12 Aug 1884 in Illinois, Roy Albert Knight b. 11 Mar 1889 in Nebraska, and Leslie George Knight b. 15 Aug 1890 in Colorado. Eventually the family ended up in Washinton state in 1898. Obviously they had to come through Missouri and Kansas but more than that I don't know.
William had three sisters and a brother, John, but he died young. His sisters were: Margaret b. 3 Oct 1849 in Indiana, Mary b. 6 May 1861 in Indiana, and Sarah b. 16 Mar 1863 in Indiana.
Margaret married a John Brown in 1869 and had a son Charles b. 11 Aug 1870. Mary married a William C. Young in 1880. I don't know if they had any children. Sarah married a Frank Myres in 1879. Again I don't know if they had any children.
William's father and mother were Barnabus Knight and Louisa Jan(Janet) Hacker and Barnabus's father and mother were Adam Knight and Mary (unknown).
If any of this is helpful please let me know.
