I graduated from Logan, Phillips County, KS high school in 1970 along with a Frank Horn, whose family lived east of Logan near Speed. Phillips County borders Graham County to the northeast, so perhaps the Phillips County Horn family is related. If you email me privately, I can give you names, address and phone numbers for Horns in Logan, Phillipsburg and vicinity. Also you could contact the Phillips County Genealogy Society. Their address is listed on the Phillips County KSGenWeb page. Ardie
