I have quite an extensive data base for the Burnell Family having worked on a Genealogy of this family. These Burnells appear to be of Baldwin, Maine. Samuel mentioned was born in Gorham, Maine and died in Baldwin, ME; Mary, Susan, Rebecah, Thomas, Deliah, Jonathan, Sally, Benjamin, Ruth, Amos, Eleazer, all children of Samuel Burnell (above) and his wife, Amy Irish.
Mary married Edward Richardson; Susan & Rebeckah died unmarried; Thomas married Lydia Butterfield; Delilah married Ezekiel Milliken; Jonathan married Martha Hall; Sarah "Sally" was not married but did give birth to a daughter, Jane, 1824; Benjamin married Ann Libby; Ruth unmarried; Amos married Abigail Cotton; Eleazer married Abigail Batchelder;
I believe that Emma listed was a daughter of Jonathan & Martha Hall. (she was b. 11 19 1828)
