The 1880 Meachams Atlas of Prince Edward Island shows this property belonging to Alex. Beaton with 250 acres. I appears the East Point Lighthouse is on this property out at the point. Below see the lighthouse keepers list - Alexander Beaton was the first and third keeper.
By the time the Cumins 1928 Atlas of Prince Edward Island was published the property changed ownership to the Cameron Brothers.
East Point is located in Lot 47.
Below is the map of East Point from Meachams 1880 Atlas of Prince Edward Island showing the Alex. Beaton property and lighthouse.
