Eileen...Daniels/Varney challenge. Early Vermont/New York

Looking for information on my 3rd great grandparents Obadiah Daniels/Mary Anne Varney. I believe they may have been from New Hampshire originally, but that is speculation on my part. I have very little information on them. Obadiah born perhaps mid 1700's. Mary Anne born perhaps 1800/1805. I believe Obadiah was quite a bit older than Mary Anne. They had eleven children; the first a daughter Sarah, born maybe Stockbridge, VT. about 1816; the last was a son, William, born Nov 30, 1844 in FT. Ann, NY. Two of the children, sisters, were my great great grandmothers. I know in 1830 they were admitted as members of the church at Middle Granville, NY. Atter the birth of the last child, Obadiah and Mary Anne seem to just disappear.
Any information on this family will be greatly appreciated. I have been caught in the same place on this family for several years. Thank you for any help.
