No longer a "long shot"! You've caught my attention and I've nothing better to pursue. Ossie's parents were John A. Lott and Mary Addison. Per https://familysearch.org/
"Florence" Wade married Ossie Lott, 4 Jul 1897 in Johnson County. Later, she wed George Sterling Hall (29 Jan 1882 - 10 May 1955) but no children resulted from this union. Per 1910 Johnson-Precinct 2-District 52-Image 42, Ossie Wade was mother of: Blanch, Reba, and Ruby. Blanch Wade Stephens (25 Apr 1898 - 2 Jan 1968) died in Forth Worth. Her daughter, only child, Lala S. Pippin was the informant. Reba aka Della Rebecca (Wade) Gilbert (2 Apr 1900 - 29 Jun 1961) wed Marian F. Gilbert and there are birth record galore found on familysearch. Didn't bother researching Ruby Wade. If you need additional help please ask? Ossie's sister Eula Evealena Holcomb (9 Sep 1867 - 16 Jan 1932) enumerated as cousin in Anne McDowell's 1900 Johnson County household.

"Ossie" was probably a contraction for Osceola?
