Among the books that dominated the year 2014—and then enjoyed a resurgence during the COVID pandemic—was E. Lockhart’s bestselling young-adult novel, We Were Liars, a psychological horror story with a deadly plot twist. Lockhart’s story, which has since been adapted for a new TV series on Prime Video, centers the Sinclairs, a wealthy Kennedy-esque family who spend each summer on Beechwood Island, a private haven off the coast of New England. There, protagonist Cadence Sinclair Eastman flits between the four homes on her grandfather’s property: Clairmont, where patriarch Harris Sinclair and his wife, Tipper, spend their summers; Windemere, bestowed to middle daughter Penny and her family; Red Gate, for eldest daughter Carrie and her crew; and Cuddledown, for youngest daughter Bess and hers.
The three Sinclair daughters are all either married with children or divorced with children. (Or, in the case of Carrie, divorced with children and practically engaged to a new partner, who brings his nephew along each summer). Given the many faces and names in We Were Liars—both the novel and the series—you might find yourself questioning who’s who as Lockhart’s mystery unfolds on screen. Are Cady and Gat related? (Mercifully, no.) Are Mirren and Johnny related? (Yes, but as cousins, not siblings.) Why is everyone but Gat and Ed so blonde? (The Sinclair genes, apparently, run strong.) The branches of the family tree reveal how wide-spread Harris and Tipper’s brood have become...and how difficult it might become for Harris to control them.
Below, peruse our quick guide to the Sinclair family—and keep your Liars in a row.
