"Patriarchy" is a word formed from the Greek word "archon" which
means "ruler". A mon-archy is a state ruled by one ruler (from the
Greek word for one, monos), an olig-archy is a state ruled by the
rich, and an-archy is a state without a ruler. From the word
"patrus" meaning "father" we get patriarchy, or rule by fathers,
just as matriarchy is rule by mothers.
No character in Romeo and Juliet is named Patriarchy, so it
makes no sense to ask "Who is patriarchy?" Patriarchy is not a
person, nor is it an adjective so you cannot ask whether Friar
Lawrence is patriarchy any more than we can ask whether he is
distance.
Is Verona a patriarchy? Likely. Is the Capulet family a
