Grandfather (his real name is unknown) is a tall, spare (lean) man with white hair he wears back in a queue and grey eyes that are soft and usually full of gentle good humor. He owns a large plantation, King's Creek with several enslaved people. He immigrated from England, along with his late wife.
Grandfather is a generous man and kind to his family. He is a strict Loyalist and finds the Patriot cause to be foolish, the ranting of irresponsible scoundrels, and disloyal to the King; he is sure the colonies will be part of England forevermore. He finds it wrong that Edward is no longer selling tea at the store, but is polite enough not to discuss it in front of other guests so as not to embarrass his daughter and her family. Felicity worries about having his good favor and doesn't wish to upset him; she feels that he understands her, in a way the rest of her family doesn't always do, and he says she has a good eye for horses. He also taught her to ride horses (though she often does not ride properly sidesaddle as is expected of her).
Grandfather catches an illness he does not recover from and dies during the events of Changes for Felicity in Willamsburg at the Merriman home.
