Peggy Schuyler's first appearance is with her sisters, Elizabeth Schuyler and Angelica Schuyler, as they sing of the Revolution; Angelica in hopes to give women more equal rights. Peggy is immediately portrayed as a rule-follower, always doubting whether the sisters should be out in the excitement while the were supposed to be at home at their father's instructions. Later on, she is seen hugging her sisters and Hamilton following Eliza's engagement to him. Hamilton also mentions that Peggy has begun to confide in him.
Shortly thereafter, however, Peggy Schuyler passes away at a young age, and as such makes no appearance in Act Two. She married Stephen Van Rensselaer IV.
- In reality Peggy was actually known as very quick-witted and sarcastic.
