I don't have an exhaustive list of relatives involved in the Civil War, but this is what I have, so far:
On my father's side:
My 3rd Great Grandfather, Wiley D. Brassfield (1827-1902) was in the 8th Regiment Iowa Volunteer Infantry, Company B. His brother Nicholas R. Brassfield (1848-1926) was also in the 8th Regiment Iowa Volunteer Infantry, Company B. A few months ago I posted a bit about what their regiment did while the were in.
On my mother's side:
My 4th Great Grandfather, Benjamin Wise Firman (1800-1862) was in the Wisconsin 16th Infantry, Company H. He died May 5th, 1862 of disease after the Battle of Shiloh.
My 3rd Great Grandfather, Ira Wood (1834-1909) was in the Wisconsin 1st Regiment Cavalry, Company G.
I'm sure there are some more relatives that I haven't found yet, but I'll keep looking.
