Timothy O'Connor is not buried in Arlington National Cemetery. There is and "In Memory of" headstone for him.  (MF10-3 T17).  It is just feet off of Porter Drive at Roosevelt. I stumbled upon it by accident when I was taking photo's of the headstone's of two of the Pentagon victims.

I have tried to find out the history on him with little luck.  He died on 10 January 1868 (DOB:1 January 1848).  He entered the service in 1863 and was discharged in 1865.  The citation for the Medal of Honor is of little help, as you know. The headstone was based on a request from someone, and approved by Arlington National Cemetery officials. It was installed on 9 March 2000.
