Interesting. I keep finding that it's a male personal name, but no one seems to know what it means. The spelling "Sherjeel" is "spark" in Arabic, but "Sharjeel" which is said to be Urdu, Pashto, Aborigine or Estonian in different name banks, doesn't have a meaning listed anywhere.
Shumaila (Arabic/Persian/Urdu:شمائلÛ) (IPA:ʃʊmaËʔɪlÉ™h) is an Arabic female Muslim name meaning beautiful face.
