Kentucky and Missouri Laughlins

I'm researching the JOHN HENRY LAUGHLIN family from Madison County, Kentucky. JOHN HENRY LAUGHLIN died there in 1812 and his son JOHN moved to what is now Camden and Pulaski County Missouri a short time later. They had 10 children, one of them being LETITICA LAUGHLIN, my 3rd great grandmother. My LAUGHLIN family often married into the WALKUP family as well.
