Felicity King is the daughter of Alec King and Janet King, sister of Dan King and Cecily King. She is famous for her culinary skills, much to the chagrin of her nemesis Sara Stanley who can't cook. She is a reputed beauty, and Roger King's hired boy Peter Craig is in love with her.
"Felicity was twelve. She had been called after Aunt Felicity, who was the twin sister of Uncle Felix. Aunt Felicity and Uncle Felix, as father had often told us, had died on the same day, far apart, and were buried side by side in the old Carlisle graveyard.
"We had known from Aunt Olivia's letters, that Felicity was the beauty of the connection, and we had been curious to see her on that account. She fully justified our expectations. She was plump and dimpled, with big, dark-blue, heavy-lidded eyes, soft, feathery, golden curls, and a pink and white skin–"the King complexion." The Kings were noted for their noses and complexion. Felicity had also delightful hands and wrists. At every turn of them a dimple showed itself. It was a pleasure to wonder what her elbows must be like.
"She was very nicely dressed in a pink print and a frilled muslin apron; and we understood, from something Dan said, that she had "dressed up" in honour of our coming. This made us feel quite important. So far as we knew, no feminine creatures had ever gone to the pains of dressing up on our account before." - The Story Girl ch.1
