Might be time to resolve a long standing problem. Had the same problem a few years ago. Wife an I are third owners of the house. Second owner did a bunch of remodeling including electrical. Nothing was labeled. Finally bit the bullet. Wife and I spent one day turning off circuits and labelling. In the end, you'll be glad you did. Well worth the investment of time.
A big PLUS-1 on this post.
Im 2nd owner, and had no idea which room was Amanda's bedroom(grin). Come to find out, it was the SW corner of the unfinished basement. I took it a step farther, followed each wire, did a diagram of each circuit so I knew the entire path for each breaker. Has helped me many times over the years.
