Well, I received my order today. It was quickly handled, I'll say that much.

The information I received was from the Illinois Civil War Muster and Descriptive Rolls Database. The information was for Peter Barbear, and it is as follows:

All other information such as Residence, Last Paid, etc. were left blank.

This is the extent of the information forwarded to me, and I can't even be positive this is my g-grandfather, Peter Barbie, although he was born in France, he lived in Chicago, and the age seems about right. So my guess is that this is probably him.

Kerry, thanks again for the education. Sorry I couldn't have given you better news, but that's pretty much what I expected.
