In our family tree for the Howard’s of Daniel’s Cove, we have a Mary (Polly) Howard, who was born in 1837 and died Aug 7, 1925 who was married to a Daniel Broderick of Grates Cove on Nov. 1, 1862. There are also a couple Names of Teachers at the Daniel’s Cove School: 1903&1904 Margaret Broderick (of Grates Cove) and 1905 Mary Broderick (of Grates Cove). Which I assume they are the same people, just written different on the register. Not sure if that Daniel Broderick lines up with your Daniel Broderick, but thought I would share.
