During late 18th and early 19th centuries, the rise of the coastal schooner trade and whaling ushered in a long period of prosperity for coastal towns in New England, which continued unabated until the Civil War. The War of 1812 provided many Marion sailors and sea captains with the chance to experience life at sea with privateers papers issued by the United States government, these captains went to sea in their schooners to hunt down British ships, plundering them like pirates. One of these captains was Ward Parker Delano (1819-1867), who lived in this house overlooking Sippican Harbor. The house likely dates to the mid-late 1700s and was probably originally built by his grandfather, Captain Stephen Delano (1749-1821). Under subsequent owners in the Delano family, the home was modified on numerous occasions in styles popular at the time until the early 20th century when it was Colonialized, which added the portico, gable, and dentils, possibly by Ward Parker Delano II (1851-1915) or his son, Ward Parker Delano III (1883-1940) descendants, who summered at the old family home, and were both prominent architects of the early 20th century.
