While it's not obligatory to change a non-inappropriate name (Changing my name upon conversion), it can still be desirable for the purposes of fitting in.
Question: How should a convert go about choosing a Muslim-appropriate name?
In my case, Rebecca appears in the Hebrew Bible, and being a Muslim named Rebecca seems to puzzle both Muslims and Jews, so I'm considering adopting a new name (even if just informally). I have some ideas, e.g., I like "Jannah" (جنّة) or maybe "Becca" which is short for "Rebecca" anyway (Are Mecca and Becca the same places?), but I have no idea if these names are any good.
Since the Prophet chose some of his wives' names, a possible option is to wait until I get married and let my husband choose mine.
