"General" is the son listed as G. F. M. in 1900; presumably the full name of both father and son was General Francis Marion.
Myrtle and Virgie are daughters of Grover Cleveland McClurg and his first wife Nora T. Horner. (Grover was a son of Marion by Sarah Amanda Thomas, and had recently married his third wife, Mollie Pettit, in 1910.) Annie Parker is the daughter of Eva McClurg and Nickell Parker, whom Eva married about one year after this census was taken, in May 1911, and died 6 months later in childbirth with their second child.
This is the last census record for Marion; he died in 1913.
His death certificate records Marion McClurg, age 73 years 5 months, birthdate blank, farmer, married, died 13 Nov 1913 in Pine Grove precinct, Rowan Co., Ky, father Alexander McLurg, mother’s maiden name Elizabeth Johnson, both born in Ky, cause of death what looks like “chronic Leueth”, but is probably meant to be chronic heart disease, informant Tom Clifford, Triplett, Ky, burial in McClurg graveyard.
His wife's death certificate records Miney M. McClurg, age 83 years 5 months, born 17 July 1850 in old Virginia, widow of M. McClurg, father J. C. Carvin, mother’s maiden name Malvina Carvin, both born in Virginia, cause of death old age, informant Everett Clifford, Triplett, Ky, burial in McClurg Cem.
The death certificates of their children John, Eva, and Lewis, however, all give their mother’s maiden name as Corbin.
