Now that we have the 1860s Canadian Militia, it seems that some Fenians could be useful. I imagine they would not be to hard to make, being bascially ACW infantry.
We won't be adding any specific Fenian troops, as they all used Union gear anyway, so the ACW codes will be fine.

A mix of Union and Reb, infantry and dismounted cav, painted in blues and civilian colors, with some green jackets or facings, would do the trick. More info can be found on the Fenian Raids Yahoo group:
