Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

Looking for any records of ancestors with last names "Lensky", "Wojdylak", "Peruski", and/or "Rzepecki"? All of my grandparents emigrated before 1900 as young children or teens. Most died before I knew them well. I appreciate any help you can offer. Thanks! Gregory (Lensky) Lynne, USA cf.: wikitree.com/index.php?title=Lynne-40&public=1

BTW: I recently saw the film Ida. I realize it embodies the raw wounds Poland has suffered since my ancestors left it. Trust me: The "religious freedom" my Roman Catholic ancestors' parents and grandparents thought they would find in the USA is nothing but indifferentism and heresy galore! If "Ida" were to visit 2016 USA she would go back to the tranquility and peace of the convent in which she was raised!

Which of these spellings (or an alternate?) is the most-likely correct one? I don't have a clue.... I've forgotten whatever I was told--if it was ever correct to begin with...that person is long-deceased.

Rczyepeki or
Rzepecki or
Rezepecki or
Ryczpecki?

Thank you!
