Who has a your name?
It depends on the last name. You could be related to someone with he same last name as you and never know. My last name is Alperin, and it is actually very common with Ashkenazi Jews. I hope I spelled that right. But it usually appears in different variations, (i.e.) Alperin, Alpern, Halpern, Halperin, Alprin, Halprin.
