Susannah HILDRETH b.c1783 ME m. Francis DOUGLAS[S] of ME

I am trying to determine if Susannah HILDRETH was born in Lewiston, ME as a few online genealogy sources say.However they don't cite a reliable Source that I can see.
She supposedly died June 28, 1847 and prob. in Maine but not sure.
Her Parents are given are Paul HILDRETH of Dracut, MA and Hannah MERRILL of Nottingham West, NH.
Francis DOUGLASS and Susannah HILDRETH are my 5th grt. grandparents and I would like to have as accurate info as possible on them.
Susannah's brother David HILDRETH m. Esther MOODY supposedly a daughter of Samuel MOODY and Hannah SEVERANCE of NH > eventually to Industry, Franklin, ME. These MOODY's are of the Clement MOODY line of Exeter, NH which DO NOT link to the Wm. Moody line of Newbury, MA.
If anyone can help me set some of these records straight I would be most greatful.
Thank You.
