It's not a pseudonym, but that doesnt necessarily mean she's Arab or Muslim. Aisha is from New Zealand and I always thought kiwi's were notorious for giving their kids unique, sometimes even weird names.It's no secret that many names are pseudonyms.
"Hotdogs" among many other examples of fake names for one reason or another.
If it really is Aisha maybe there is an Arabic connection then if not Muslim.
If it isn't then it's an interesting choice of pseudonymous name.
I can tell you for kiwi's, at least, name origin does not always correlate with ethnicity, beliefs etc. I know this because I am half Maori myself and my cousin (also Maori) named her kids;
Lanesha (derived from the combination of the pre fix "La" and Aisha of Arabic origin.)
Karma (Indian origin meaning Destiny)
and Kanye (female, Swahili origin meaning "only/special one")
Awesome names IMO but none of which have any connection to actually being Arabic/Indian/Swahili
