William M. Owen was born in 1816 in Albany County, New York.
William left New York and eventually settled in western Michigan sometime before 1862.
William stood 5’8” with gray eyes, dark hair and a “healthy” complexion and was a 46-year-old farmer possibly living in Ionia County when he enlisted in Company D, on February 11, 1862, at Saranac, Ionia County. (He is not listed in the 1905 Third Michigan Regimental history.)
(William may have been related to Isaac Owen who had enlisted from Ionia County in Company E the previous year. Company D was composed in large part of men who came from western Ionia County and Eaton County, while Company E was composed in large part by men from Clinton and Ingham counties, as well as parts of Ionia County.)
William, was absent sick in the hospital from August of 1862 through October, and discharged on January 14, 1863, at Fortress Monroe, Virginia for a scrotal hernia on the left side.
It is not known if William returned to Michigan after his discharge from the army. No pension seems to be available.
