There's a website called peoplefinders.com that shows a Harley B Booker was in Gallatin, MO. Unfortunately, this is a 'pay for details' site and there is no other information shown for free. No age or possible relatives shown. This site doesn't remove people when they're deceased so it could be one in the same Harley or a different one - but it does place a Harley Booker in Daviess County. Is Leroy Allen Booker one of Harley's children? There is a Leeroy A Booker (born CA & age 61) shown in several locations in TX on this same site. Do you have Harley's death certificate from Texas? Good Luck with your search. Linda S Auburn, CA
