Who was the "Widow McNiel" (probably "McNeal") who was enumerated as a household head, age 45 or more, in Rockingham, Windham Co., Vermont in the 1800 census, with a male and a female, ages 16-25? Whose widow was she? Where was the family in 1790? Was she the female, age 45 or more, who was enumerated in Rockingham in 1810 in the household of "Wm" (William) McNeal, age 26-45? Was William her son? (Note that she had a male, age 16-25, in her household ten years earlier.)
