The answer is: large, extended family
In the lines from "My Last Duchess," by Robert Browning, the speaker complains that his late wife did not truly value the social grandeur of her marriage. In that matter, he considers his aristocratic family superior to the men's she used to thank. However, she did not realize and acted as if other men's favors were just as important as his, who has a family which is more prominent and higher in rank.
