I have a letter written by a Goddard whose brother or father (not sure which) was one of the original organizers of the IL Rebels. He and his brothers ended up joining Federal Infantry troops. John Goddard was a prisoner at Andersonville. John's brother, George, wrote this letter to another brother. It doesn't mention the IL Rebels though--just that the war had changed and he wanted out.
I may also have information on some of the burials that aren't in the book. I've tried to locate the owner of the Metcalf papers, but haven't had any luck.
The Lynn who owned the hotel near Pellonia (Brooklyn, Brookport) is mentioned in an old newspaper clipping (spelled his name Linn). This is where the men were almost captured prior to crossing the river. According to the book, this hotel was west of Metropolis, but other sources show that it was east. There is also mention in the OR of Confederate uniforms being found in a boat near this area for the same time period. It was suspected that the uniforms lay in waiting for the men so they could cross the river into KY.
Another "Lynn" (Wm) also owned a hotel there, but was a Union man.
