John,
Were these men half-brothers? I notice they have different last names or am I misreading the post?
I have found men by these names in Virginia units, but I'm waiting for some of our other contributors to respond to you, rather than, jumping in myself.
Do you know where these men lived in 1860? That information will help us cross-reference soldier indexes and county enlistment information. This information can help to confirm which man is yours.
