Smith’s grave is on private property in Gorham and the location has not been disclosed. The ceremony, which also will be private, will feature an actor in Colonial era costume along with speakers from the museum, Revolution 250 and the Massachusetts Historical Society.

Smith’s grave is one of 10 in nine Maine communities to receive markers this month in advance of the 250th anniversary of the Boston Tea Party next year. The museum so far has placed 104 grave markers throughout New England, it said.

Hearing of museum plans for a ceremony, Gorham historians located Smith’s grave in late August following a stepped-up search after town and cemetery burial records proved misleading.

Smith, born in 1751 in Massachusetts, was a 22-year-old sailor and the husband of Elizabeth Harding  when he was among a group of about 150 people who heaved tea overboard from British vessels. He became a ship’s captain and moved to Gorham where he died at 84 on his farm.
