I have info on three Darius Danns. The one you are referring to I am assuming is the Darius Dann born 1828 in NY, son of Ebenezer Dann, Jr. & Serepta Goodrich.
The other two would be 1) Darius born 1803, son of Ebenezer Dann, Sr. and wife Sarah Jones (sister of my Josiah Jones) who married Minerva Seeley & 2) Darius Dann born 1829 NY, son of Amariah Dann (son of Ebenezer Sr & Sarah Jones) and Nancy Purvis, who married Phidelia/Fidelia Turner.
If anyone reading this is interested in their JONES ancestry off this Dann family, please let me know.
