Woodruff's from Farmington, Hartford, CT to Lewis NY

Am seeking information as to what might have MOTIVATED MOVE OF Constable Appelton Woodruff (b. 6-1771) and wife Mehitabel Churchill who left Farmington, Hartford, CT, FOR LEWIS, ESSEX CO., NY. I am descended through this couple's fifth child, Thusa Woodruff who married Job S. Manning.

Appleton's lineage backward is:Appleton W. & Dinah Hart, Josiah W. & Sarah Woodford, Joseph W. & Hannah Clark, John W. & Mary Winchell, Matthew W. (Pioneer from England to FArmington, CT) & wife Hannah Baldwin, Matthew W. & Margaret Sander in All Saints, Cambridge, Essex, England (alternate lines offered subtitutes Sir David Woodruffe for Matthew W.), althouth available documentation seems to support the Matthew W. hypothesis.
