I have Laverty ancestors in the area during that timeframe. James Laverty and Mary Laverty (nee Kelly) had children Robert (born 1868), Charles, Thomas, James and Mary (maybe others?). They may have lived in Toome, but definitely resided in Drummard Townland. Later, son Thomas moved to Tamlaghtduff.
Our line is descended from Robert Laverty (b. 1868, d. 1922). He married Catherine Leadon, had seven children and operated a shoemaker's shop in Belfast prior to 1920. Due to unrest in Belfast, he and family moved to Bancran Glebe prior to his death in 1922.
