William McIntyre was born in 1838 in Medina County, Ohio.
William left Ohio and came to western Michigan sometime before the war broke out.
He stood 5’10” with hazel eyes, dark hair and a light complexion and was a 23-year-old farmer probably living in Kent County when he enlisted in Company F on May 13, 1861. He was discharged for consumption on September 22, 1861, at Arlington, Virginia.
After he was discharged from the army, William may have returned to Michigan, although this remains uncertain.
No pension seems to be available.
