Legend has it that the ghost of Captain James MacNabe who was killed in the rebellion of 1837, wanders through the cemetery. More about this.
A story written in The Belleville Intellegencer in 2009 seems to be about the same Captain. Although the name in the article is McNabb, the date on the stone seems to match the one in the story.
