Rachel knows that Kit, as a young woman in New England in the 17th century, has no other options for finding a stable life. So, she urges her husband to let Kit stay. Matthew, however, is much less sympathetic, which again shows how Rachel and Matthew have very different values. While Rachel believes they should welcome their niece, who needs help, Matthew is unfriendly and wants to check her political affiliation first. He does so by asking Kit what her grandfather believed; he likely knows that Kit shares her grandfather’s politics and doesn’t have her own opinions. New England women can’t vote or participate in government, so Matthew probably assumes that Kit doesn’t have independent thoughts regarding the current political situation.
