"Chebeague Island is the largest of the islands in Casco Bay, near Portland Maine. Everyone knew everybody else on the island, and if they were not related, they were friends, or at the very least knew everything there was to know about each other, including what they had in their stew pot at any given time. Most of the islanders, including the Kimberly family, were descendants of the “Stone Sloopers.” On Chebeague Island they built three wharves. The Stone Wharf, or Hamilton Landing as it was known, is still in use today. The one-masted sloops, sometimes known as Chebacco Boats, sailed along the rocky Maine coast transporting granite and stone from Maine’s coastal quarries, to east coast cities as far south as Chesapeake Bay. The Washington Monument and many of the governmental buildings in Washington, D.C., were built of granite brought up the Potomac River by the Stone Sloopers. During the 19th Century, they also supplied rock ballast for the sailing ships that came into New England ports. The Stone Sloopers are also remembered for building Greek revival homes, which can still be seen on the island.”
