The Supplementary Daggett / Doggett book clears up the Electa Furber Daggett question. Electa Furber Daggett was the great grand daughter of Darius 1760 1853 and Hepsabah Dean, the grand daughter of Darius 1796 1851 and Electa Tucker, and daughter of Darius 1820 1902 and Annie Mary Kenny. She married Willard H. Caswell.

Also, Heritage Quest is free through most all State and County Libraries. All you need is a valid library card.
