William Parrish was born in 1841, possibly the son of William H. (b. 1816) and Joanna (Rose, b. 1812) .
William H. immigrated to America where he met and married New York native Joanna (or Johanna). By 1840 they had settled in Ohio and sometime between 1843 and 1847 moved to Michigan. By 1850 William (younger) was attending school with his siblings and livng with his family on a farm in Rutland, Barry County.
William stood 5’6’ with blue eyes, light hair and a dark complexion, and was 23 years old and probably working as a farmer in Barry County when he enlisted in Company F on January 4, 1864, at Grand Rapids for 3 years, crediting Barry County, and was mustered on January 8. (He may have been related to Heman Parish who was also from Barry County.)
William joined the Regiment on February 17, 1864, was transferred to Company G on February 29 at Camp Bullock, Virginia, and reported missing in action on May 6, 1864, at the Wilderness, Virginia. He was transferred to Company F, Fifth Michigan infantry upon consolidation of the Third and Fifth Michigan Regiments on June 10, 1864, and was mustered out on July 5, 1865, at Jeffersonville, Indiana.
