I cannot answer specific what you need to know, but perhaps I can
contribute with some side information that maybe you don't know yet.
Albahary is a frequent Sephardic name not only in the Balkans but also
in Morocco and other North African countries
It is an Arab word meaning ">from the sea". "Bahar" is "sea" in Arabic.
Some Jews which used originally this surname have translated in Spanish
speaking countries to Delmar, with the same meaning - ">from the sea".
There was a family Delmar in Ponta Delgada, Azores islands.
When searching the surname in any database, try also Delmar.
