Sarah is Penelope’s daughter who moves to Australia. This breaks Penelope’s heart because, even though she often complained about her raucous grandkids, she realizes she’ll miss them when they’re gone. Like her brother, Adam, Sarah favors their father, Giles. This upsets Penelope, seeing as she was the one who raised them after the divorce. Sarah suggests that Penelope take the AncestryDNA test to find out more about her birth family and later helps her connect with her birth mother, Hattie.
