Hi Dan I Was transferring my Family Tree Maker info to my new computer and found my tree fo my Grandfather William E Marsden,wuo was married to Katherine Ellen. My Aunt Grace ,Williams Daughter said Kate had a Brother Fred who was wounded in the Civil War. I went to Middletown N.Y. and in the library there in a town directory for I think 1900 ifound Fred living there.
I hope this helps your search. I also hope this is not duplication but here it is. Good luck
