The most often asked question along these lines is "Are you related to Bronislaw Malinowski?"
The next most often is "Are you related to my friend/relative/associate ____________ Malinowski in Chicago?"
Sadly, my answer to all these questions is "probably not, but I don't have any way of knowing."
My father's parents came to the United States from Poland in the early 1900s. They had two sons, Frank (my father) and Stephen (my uncle). Stephen, who died in the mid-1940s, fathered only daughters (who are now married and therefore not called Malinowski any more). Neither my brother Hugh or I have children. A few years ago, my father visited the towns in Poland his parents came from, in hope of learning something about his family history, but the records had all been destroyed in the war. So, the only Malinowskis I know that I'm related to are my father Frank, my brother Hugh, and Stephen's wife June (whom I've never met).
My wife Lisa Turetsky often gets asked whether she's related to the bass player Bertram Turetzky. The answer is the same.
