Am searching for Jonathan Hackett b. 5 Nov 1792 in Salisbury, MA son of Jacob and Marcy or Mary. The family reportedly moved to Poplin (now Fremont)New Hampshire. I believe he may be the Jonathan Hackett who married Mehitible (last name unknown), born 28 Aug 1801 in Londonderry,NH possibly in the section which became Derry. Would like to document that the Jonathan Hackett of this family is the same person indicated below and to find Mehitible's maiden name.

My Jonathan and Mehitable Hackett (my 3rd great grandparents) appear in Barnard, VT had 2 sons there, Charles Warren Hackett b. 1820 and Luther Holton Hackett b. 1823 and perhaps one or more daughters. Jonathan died between 1823 and 1830. "Widow" Hackett appears in 1830 census of Barnard. She marries Gilman Robinson in 1834 in Lyndeborough, NH althouge both are noted to be residents of Merrimack. They have a son John G. b. 1836 in Nashua.

Mehitable's parents names MAY be Dana and Sally. No probable fits in "Vital statistics of Londonderry, NH."
Any leads will be greatly apprecioated
