I was just watching the latest version of Mysteries at the Museum with a special segment on the Boston Tea Party, and it is quite possible our Mann ancestors were involved in that historical event. Ensign Mann II* (Jr.), who graduated from Harvard, was a known Patriot and leader of the Sons of Liberty in Petersham. It is believed the Sons of Liberty, along with Samuel Adams, were responsible for the event. Ensign II would have been 33 at the time. Ensign is listed in a book of Registered Members of the American Revolution.
*In some entries, this Ensign is referred to as "Jr." However, his son Ensign is also known as Jr., so I named this Ensign, born in 1740, "II." There were 3 in a row, so it can be quite confusing.
