As fictional family, the Whitehills are featured in the short stories of Brazilian writer Rita Maria Felix da Silva.
The first reference to them was Lord Douglas Whitehill in "San Juan Romero".
Kate and her partner (Ken McSmith)then returned in "Jogo de Facas" (A Game of Knives), "Cacos de Porcelana" (Porcelain Shards) and "O Legado do Demônio de Barro" (The Legacy of the Clay Demon), all three short stories written by Daniel Folador Rossi, a Brazilian writer and a friend of Rita Maria Felix da Silva.
There is a tendency of the readers to consider them as an "evil family" while other ones state is just "bad luck".
Camphill, Pennsylvania was originally called Whitehill, but changed its name during the American Civil War in respect to a group of soldiers who had camped there.
