Now you have peak my interest since I have one Briggs I can't not find his parents whatsoever.All I do know of his name is Caleb T Briggs born(We hope)in Warwick New York.Now the thing is I have asked twice if the Orange County of New York Genealogical Society of a family Briggs living near the time of Caleb T Briggs birth which was May 2,1810. Now the other odd thing is in the second census record I find my Caleb T Briggs is here in Michigan now they list him and his wife Elizabeth Ursula Morrill plus extra person a Betsey Briggs born in 1834 in Ohio.But the thing is that my Caleb T Briggs and Elizabeth Ursula Morrill didn't marry until 1836 in Jackson(Jacksonburgh)Michigan.So I having heck of time trying to find any kind of clue for Caleb T Briggs parents or even siblings if he had any.If you need to check my tree it Briggs Fmaily Tree should be public.
