Dear Kevin -- thank you for your email. I have newspaper references that PATRICK O'RORKE (sometimes spelled O'Rorke) was a prisoner at Andersonville. I do know that he was captured at the Battle of Chickamauga. He was a member of Battery D of the Michigan First Light Artillery. I would appreciate any information that you might have that would confirm that he was a prisoner at Andersonville. Jim Sebastian, Grand Rapids, Michigan
