My Northern ancestors risked their lives to help escaped slaves. One of them, joined the 19th Illinois Volunteer Regiment.
Volunteers, not draftees. Fighting for people they didn’t even know or would ever meet.
Your Union ancestors were willing to risk their lives to end slavery, do you disagree with what they did? Just because you had confederate ancestors also?
Unlike you, I respect the sacrifices they made on both sides. As a side note, I had an ancestor who died at Andersonville.
