Biography
Laura McGhee was detained in Mississippi in the context of the civil-rights movement, as documented in Charles Payne’s interview-based history.
Payne’s chapter explicitly identifies Laura McGhee as the mother of Silas, Jake and Clarence. It reports that she was arrested during a confrontation at the Greenwood police station while visiting Jake after his August 1964 arrest. The account says she apparently was not tried; that is not recorded as an acquittal. No precise arrest day, jail admission, discharge or actual duration is supplied.
