Question: what is the relationship between the two families in romeo and juliet?
Answer: The two "houses", as Shakespeare calls them, are the Capulet and Montague households. Romeo is the son of Lord Montague, and Juliet the daughter of Lord Capulet. Tybalt is a cousin to Juliet - Lady Capulet's brother's child. Both families lose their heirs at the end of the play - the younger generation is wiped out.
