How old is the movie?

Overview

It's the early nineteenth century Washington. Young adult Margaret O'Neal, Peggy to most that know her, is the daughter of Major William O'Neal, who is the innkeeper of the establishment where most out-of-town politicians and military men stay when they're in Washington. Peggy is pretty and politically aware. She is courted by several of those politicians and military men who all want to marry her, except for the one with who she is truly in love.
