I've got a sketch portrait of my husband's grandfather, James O'Connor. He was internee # 1348 or 1378 (I can't make out the writing) at Frongoch Camp. This picture was sketched by an "M. Kelly" and dated October 8th, 1916 while he and James were held at Frongoch. Would "Dublin in Rebellion" possibly contain any information on James O'Connor?
