Two households, both alike in dignity, in fair verona, where we lay our scene, from ancient grudge break to new mutiny, where civil blood makes civil hands unclean. what is the best way to paraphrase these lines?

two ancient feuding verona families shed more blood.
two families fight over whom pretty verona shall marry.
two feuding families in verona have an ancient grudge.
two old families in verona fight and get themselves dirty.
