Ottoman Turkish inscription: Need single word translated

[Zifir]

That forumite is also shilly-shallying about his reading of the script If I am allowed to correct my mistake, it is B and H (I think). I can't find suitable vocalization for this word though. Assuming this is a specific Caucasian name, rather than a Turkish one, all we need is to find someone who is familiar with languages and names of that area.
