I wouldn't mind if people wanted to use BellLocke as their pairing name in general tbh, but "Locke" is based on the name I gave her horse in my AU so ig you'd all have to collectively decide her horse is named Locke or just not think about that part of it haha.

For context: Micah helps her steal Locke in ch4 because he's annoyed that, since they keep going out together, Baylock has bonded somewhat to her and she keeps taking him without asking; and then later on after ch6, sometime in 1903, he kills Locke to strand her once she tries to flee from him so that he can drag her into Hagen. Locke's death, her pairing name's sake, marks the moment she loses her agency in the pairing. So it's extremely contextual to the AU but yeah, idrc. I don't think they have a pairing name otherwise.
