Yes , only in Northern Italy will you find Italians without vowels at the end of their last names LOL . Some say the names got butchered at Ellis Island (highly possible) , some say it's because of the close proximity to Austria , Germany, & France (mating with non Italians ? That screws up the lineage when it comes time to be inducted/made no ?) which always raises the question whether or not certain families from Northern Italy are actually Italian by blood or just relocated during WW2 during the Hitler/Mussolini alliance . The name Senter actually sounds to me like it could be German or Austrian honestly .
