'ICHABOD FRANKLIN ... m.(2) 17 March 1779 Winchester, NH VR & Chelsea, VT VR, HANNAH (-) FRANKLIN.'
Chelsea, VT was not settled until 1781, so this marriage likely took place in Winchester and was also recorded in Chelsea after the family moved there.
'1777 ... Ichabod Franklin m. Hannah Franklin Mar 7th.'
The year is clearly stated as 1777, which is before the death of Ichabod's first wife. Either the year is wrong and should be 1779 as suggested by Jenks & Seymour, or this was a different Ichabod Franklin (or Ichabod's first wife died earlier - but she supposedly had a child in 1778).
