Language / "Szurszewski" - How to pronounce my last name correctly? [7]

Hi everyone,

I am an American (3rd generation Polish) trying to figure out the correct pronunciation of my last name:

"Szurszewski"

In English, is it closer to "Shur shev ski" or "Shor shev ski"? (Shur vs. Shor; u vs. o sound)

Thanks a bunch.
