McCorkle's in Ky.-early 1800's

I've hit nothing but brick walls trying to locate the family of my ggrandfather, Elmer E. McCorkle b. 1868.Your Elmer E. peaked my curiosity. Could this be the same Elmer E listed in your posting?Where was the 1880 census you referenced?Our records indicate Elmer Ellsworth McCorkle was born in Johnson County, Iowa.Would love to hear from you and explore the possibility of a connection.
