Hello. I noticed your post today on this forum. Your husband, then, would be a male Orr descendant. Have you or he considered taking the Orr Family Surname Y-DNA test? I am an active member in the DNA program, and have found much help with this.
I am working to figure out several Orr families that resided in Mecklenburg, NC, before 1800. Your family line of Orrs and mine might be related, but unproven at this point. A DNA test might gives some more clues on how the Mecklenburg Orrs are related.
