Four skeletons discovered under a house in Ridgefield, Connecticut, could be a rare historical find. They may be from soldiers who fought in the Revolutionary War (1775-1783), experts say. Clues include metal buttons found on three of the skeletons and the bones’ location. The house, built around 1790, is close to where the Battle of Ridgefield took place in 1777. Experts hope to determine whether the men were Revolutionary soldiers by studying their buttons and teeth. If they were, historians hope to solve another mystery: Did they fight for the American colonists or the British?
