Henry Pelham (1749-1806)

You come from an artistic family and follow in your stepbrother's footsteps as a portrait artist, but you remain in his shadow.
Paul Revere, a friend of yours, plagiarizes your print of the Boston Massacre, robbing you of the credit.
You are seen as a Loyalist because of family connections, making you a target of Patriot intimidation tactics.
You move to Britain and forge a career as a civil engineer, cartographer, and astronomer.
While overseeing a construction project, you tragically drown.
