The only occurrence of a name like this is the pre-Islamic poet whose name was Waddaak bin Sumail, it is literally Thumail, but since Th is difficult to pronounce, it is often read as Sumail. It is a non-Quranic word, and it could have various meanings. It is unclear for which meaning the name was used, for example it could be "water that remains in pools on rocks after it rains", "small grain of wheat", it could also mean "the best man in the tribe".
You can use Sumail as a name since it doesn't have a bad meaning.
