Currently they aren't connected. I can see that you are hoping to trace Deans-557 back, and join them to Deans-360. You may or may not be successful. Just focus on getting Deans-557 back, because you may find that they don't connect in there, and we don't want to fit someone in falsely. I'm not familiar with sources in America. Hopefully someone can find some more clues for you, certainly in the North Carolina area.
By the way, if you can, edit the question, and under TAGS, add DEANS, add BRICKWALL, add NORTH_CAROLINA. This will enable your question, to be sent to the people working in those areas.
