Lisa, I do not believe that Lewis Peavler died in Mercer Co. KY, in 1854, but may have been visiting his sister-in-law, Catherine Yeast Peavler at that time. He may have died in Knox Co. KY or in MO. In April 1854 he submitted testimony on behalf of his sister-in-law Catherine Yeast Peavler and her brother, Leonard Yeast, married to Elizabeth Peavler,in regard to her application for American Revolution pension application. Catherine Yeast was married to Christopher Peavler/ Pevler (he died in 1836). I hope that helps you in your research.
