They are said to have a daughter, Abigail; the only slot left for her in the census is ca. 1794.

At Ancestry.com, North Hero, Middle Hero, and South Hero were misindexed, mislabeled, and misgrouped as being in Franklin County (correctly done at Genealogy.com, i.e., in Grand Isle Co.).  Middle Hero is now Grand Isle.

*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25, which means any individual in column three is duplicated in column four.  So, for an accurate representation of the household, the number in column three should be subtracted from the number in column four. If, after the subtraction, any individuals remain in column four, then they have to be age 19-25, thus creating a "new," more precise age class.

Peter is supposedly married at this point, but I don't find him as head-of-household in the census; it appears he and his wife may be living with his parents.

These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	20-29	1800-1810	= ?
1 male	60-69	1760-1770	= Warren (b. 1769)
1 female	15-20	1810-1815	= ?
1 female	20-29	1800-1810	= Elizabeth (b. ca. 1807) = Phoebe (b. 1804)
1 female	60-69	1760-1770	= Huldah

It's hard to figure just who is in the household at this point.  They had no son born after 1800 and no daughter born after 1810, so who are they?  Phoebe and Elizabeth aren't married, yet, so we'd expect to find both of them.  One of the girls might be fibbing about her age, which would account for the younger female, but what about the young man?  Is he the unknown male from 1820?

6.  1840 Census Index/Images (online at Ancestry.com):  not found.  There is a woman age 60-70 living in Grand Isle with our subject's son, David.  Some have taken this woman to be Huldah, but Huldah should be a decade older.  The woman could just as easily have been David's mother-in-law as his mother.
