Question:

What nationality is the surname "Bartolowitz"?

Does any one have this last name, where did originate? I'm not sure if it is German, Polish or maybe Jewish

Best Answer - Chosen by Asker: Names have no nationality. A person is a citizen of a nation. Only careful genealogy research back one generation at a time will reveal where your ancestors came from, if that is what you meant to ask.
