Pick a name: Broswich or Brozvik?

Hello, I am winning my brother's firstborn child namings rights in court case stemming from a card game on vacation 12 years back. I'm going to name my nephew either one, Broswich or Brozvik: We are Hungarian and live in the upstate New York region. We either are using common spelling from mother's side of family or father's, which one looking more American or “of the land”?
