From William G. Cutler's History of the State of Kansas, published 1883, A. T. Andreas, Chicago, IL. Coffey County, Early History:
Morgan Dix came to Coffey County in the spring of 1855, from Indiana, striking the Neosho River at Le Roy, and passing up the river by the way of Stubblefield's, he settled near Ottumwa early in the spring of 1855, and lived there until he died in 1874. Hiram Hoover, Judge Strawn and Joe Lebo also settled at or near Ottumwa the same spring ...From The Leabo Line, Descendants of Francois Isaac (LeBas) Leabo
Josiah Leabo (Josiah2, Francois Isaac (LeBas)) was born 12 May 1831 in Indiana, and died 08 Jan 1895 in Hartford, Kansas. He married Mary Jane Crail 12 Feb 1860. She was born 30 Nov 1839 in Vermont (Fulton) Illinois, and died 19 Feb 1913 in Hartford, Kansas. ...[T]he town of Lebo, Kansas was named after Lebo Creek where Joe Lebo lived. He was a freighter and had been a Captain in the 10th Kansas Cavalry. It is believed that Josiah and Joe Lebo are the same person
That's it for now.
Note to myself. Burlington, the county seat will have a record of Joe Lebo's land title. There is a nice library in Lebo.
