William A Johnston died 3 September 1915 in Streator, La Salle Co. His obituary stated that "interment will be made in Pontiac, in the family lot, the funeral train leaving over the Wabash at 10 o'clock". His first wife was Anna (Duff) Johnston who died 4 November 1889. Her parents, Charles and Eliza Duff, and her brother Jonathan Duff, lived in Pontiac. Could anyone tell me what cemetery the Duffs and William A Johnston are interned? Thank you
