Senter is an Italian name it's not extremely common but there are indeed Italian last names that don't end in vowels and not meaning the people who had it taken off. Like HN said its names like Senter for example, or DeAngelis that can be found more in the northern regional area of Italy. Good example:Furio Junter
You make a great point about not all Italian names ending a vowel, Southend. Like you say, it's not just the ones that are shortened, either. I know a whole clan of DeRobertises who still use that name in the Basilicata region. In America such a name might have become Roberts way back when.
But you picked a poor example to demonstate your point. Furio's last name was Giunta:
