Who begins to pay Kit weekly visits in Chapter Seven of The Witch of Blackbird Pond by Elizabeth George Speare?

In Chapter Seven of Elizabeth George Speare's The Witch of Blackbird Pond, William Ashby visits Kit at her Uncle Matthew and Aunt Rachel's home. Kit finds this encounter utterly boring, as William seems happy to just sit in silence as Kit awkwardly tries to make conversation. William only begins to show some spirit when he gets into a debate with Uncle Matthew over surrendering the charter. 
The night ends on a sour note, with Uncle Matthew storming off in a huff. Kit is certain that William won't be back to visit her, but Judith, Mercy, and Aunt Rachel dismiss that notion by telling her that William has decided to start constructing his home, a sign that he has decided to seek Kit's hand in marriage. This horrifies Kit, who longs for someone that she can talk to.
As Kit's family predicted, William begins to visit Kit every Saturday, and she gradually begins to look forward to these visits, as they break the monotony of her otherwise laborious work week.
