We’re trying something new this week by bringing in a guest for our upcoming historical event segment. Clara Silverstein from Historic Newton tells us about their “Crossing Borders” series. Sticking with the theme, our show this week recounts a romance between young lovers that crossed enemy lines and political allegiances, uniting patriot Billy Tudor and loyalist Delia Jarvis. Even as the Revolutionary War began and Boston was besieged, Billy risked everything and swam across the harbor to visit Delia. As the war continued and they were separated by many miles, Billy would address his letters to Delia to “my fair loyalist,” and then sign them from “your ever faithful rebel.”
