This family is a perfect match for Anson Fox in Trenton. What I find even more interesting is that Anson was born in Connecticut. We also learn his parents names are Reuben Fox and Hannah Williams. This family sketch also states Ansel was born in Cornwall, Connecticut which is in Litchfield County. I copied the 1820 Trenton census with the names from the above sketch so you could also see how well the information matches.
If the list of children are correct, Ansel should be in Oneida County in 1810. The only problem with the 1810 census is that only the first initial of the first name is listed - for everyone! I just hate that. However, you have to work with what you have. I have yet to locate Ansel in 1810. In 1800 he is still living in his father's household in Cornwall, CT. I have clipped the census page below. The names and dates are from the Barbour Collection for the births in Cornwall, CT.
The birth date for Reuben Fox come from the Barbour Collection births for East Haddam, CT. The only child I couldn't find is Levina Fox. She was born in 1773 and most likely would have been married by 1800, assuming she lived.
