Hilanthis is different than the "Highland" another person submitted. I know one lady with this as a first name. She said it was her grandmother's name and she knew no other spelling. If it is a derivative or mangled form of "Highland," I like Hilan better, as it is pronounced differently, has a smoother softer sound.
This name may be a form of Hyland, an English surname derived from Old English elements heg "high" and land "ground; land." It was probably originally given to denote someone who lived on a high patch of ground.
