The -inthos endings means "place of", and appears in Corinth (the Place of the Carians) and is found scattered around the Mediterranean. As VR said, there's a longish inscription on Lemnos (not surprisingly, called the Lemnian Stele, and FR has a keyword for that) that appears to be in a language related to Etruscan, or actually is a dialect of Etruscan.
Another inscription in the same language was found on Lemnos in 2009. It seems to be on the side of a stone lid to a sarcophagus (the photo I have seen seems to show a man and his wife facing each other while lying down—similar sarcophagus lids are known from Etruria). It’s shorter than the other Lemnos inscription.
