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

My father said his family had the surname " Bień " in Poland as far back as he knows. He had one sister remaining in Lvóv up to 1977, no other remaining family. He said maybe some French people moved up when the a French Queen came to Poland. Is this true?

Do you know where the name "Bień" came from? Are there any people left?

My Mom's surname is Stępien, any ideas on this one?

thanks for any help,
