Peter Pelham (c1695-1751), artist and engraver of Boston, is said to have emigrated from Chichester in 1726. He is reputed to be the engraver of the first mezzotint plate prepared in America. His son, Henry, made a survey of the military fortifications at Charleston, soon after the battle of Bunker Hill. He was forbidden from publishing due to the level of military detail involved, but it was eventually incorporated in a larger map of Boston and the surrounding countryside which Pelham published in 1777.

Dame Agnes Frankland, formerly of Massachussetts, came to live and be buried in Chichester in the late 18th century. Born in the small fishing village of Marblehead, Massachussetts, in 1726, she was a servant girl, of poor parents, who fell in love with a wealthy young Englishman, Charles Henry Frankland. They lived in Boston, at the centre of fashionable society. After his death she eventually came to live in England where she settled in Chichester in 1777, living at 5 West Pallant. She then remarried, to John Drew of Chichester and lived in Little London in the parish of St. Andrew Oxmarket. When she died, she was buried in the Litten graveyard in St Pancras.
