Although I'm not familiar with the person you're looking for, my father, Harold Mccarthy, might be of some help. My great grandfather was Charles Daniel McCarthy who lived here in Bienville Parish (Castor,LA) and died in 1950. His father was named Joshua and lived for some time in Mississippi before moving to Louisiana. Joshua was born in 1834 in Alabama according to an 1840 census record and he died and is buried at Sicily Island, LA. He had several children but I'm not sure of the names. We are in the process now of trying to link Joshua and his father Daniel back to the South Carolina McCarthy's who spelled it "McCarty" then. We believe that Daniel was the son of a James McCarty or a Michael Jr. but we have nothing to prove it. E-mail my dad at email@example.com
maybe he can help.
