Hello, I was wondering if anyone had any ancestry with the surnames Sielecki (or feminine form Sielecka) or Goitz (perhaps spelled Goidz)?

My records are hitting a dead end. My great-grandmother Pauline Sielecka (1894-1972) immigrated to America around 1913 with a cousin/friend I was told. Her brother Frank was already in America (I believe they came through NYC). Pauline married my great-grandfather Ludwig Goitz (1863-1948), another Polish immigrant, here.

any information would be great...Polish records are difficult to find, with all the border changes!
