My name is Tunesha. My father named me after the country Tunisia. All of the variant spellings I have encountered belong to women whose parents had the same motivation in their choice, changing the spelling because people have a hard time saying Tunisia (I actually met a girl with the original spelling and no one said her name correctly. Always saying 'Too-nee-see-a' instead of 'Too-neezsha'. It doesnt exactly roll of the tounge.) So if you want to really find the root of the name, discover what 'Tunis' means =]
