Non-muslim names from the Arab world are probably most easily found in the Arab
Christian community:
https://en.wikipedia.org/wiki/Arab_Christians (in English)
Arab Christians tend to use arabised versions of names that are commonly found in (or spread by) Christianity, such as:
• أنطون (
Antoun or
Antun), which comes from
Antonius;
• بطرس (
Butrus), which comes from
Petros;
• فرنسيس (
Faransis or
Fransis), which comes from
Franciscus;
• قسطنطين (
Qustantin), which comes from
Constantinus.
Of course, they do not exclusively use such names. They also use regular Arabic names, and then probably mostly the ones that are not strongly tied to
Islam (meaning: a name like
Muhammad will be out of the question, but something more neutral like
Jawad will be fine).
