S. C. Bozarth may be Simeon C. Bozarth, s/o Oliver Hazard Perry Bozarth and 2/w Artemisia Duggins, who were married 30 May 1861 in Grayson Co, KY.
My records show that he was married twice. I do not know the name of his first wife. She could have been your Lanivinia McGrew.
His 2/w was Cinderella Palestina "Tina" (Stone) Haycraft, the d/o Joseph P. or Josiah B. Stone and Artemesia Sands and the wid/o John Samuel Haycraft, who died in a gun fight on 10 Feb 1893. Simeon, 37, and Tina, age 42, were married 1 Jan 1902 in Grayson Co, KY. Their marriage was recorded on page 75 of Book 6.
Let me know if any of these records are in any way familiar to you.
