This may not be much help, but just in case I will pass it on. William Leslie Willis married Nov. 23, 1920 in Adair Co., KY to Cornelia Irene Conover (b. Dec. 12, 1885) dau. of Robert Conover and Cornelia Minor Johnston. William L. Willis and Cornelia had dau. Helen Irene Willis who married Edward Newton McKinney. They lived in Adair County just south of the Cumberland Parkway and west of Columbia. Helen McKinney had an interest in genealogy and family history. A distant cousin met with her back some time about the 1980's? and she provided him with a picture of her g.g. grandfather on the Johnston side. I do not know what other such things she may have or if she is still living.
