David,
Sorry I haven't been following this lately--lost track.
Your information matches mine (some dates are slightly different), except that Alice's last name is left blank in all the recent research I'm aware of. Do you know that someone has proven her name to be Kellogg? Do you have a source you're willing to share?
My info. comes from a researcher who studies the early families of Fairfield County, CT, and who cites articles in The American Genealogist, and Jacobus' book, Families of Old Fairfield, as well as the New England Historical and Genealogical Register, vol. 51.
And to Mccluec1, I haven't heard anything about a Alice Pratt, but generally the early American "Johns" are listed as "Bouton," or "Bowton," as it is/was often spelled in England. In my family, Bouton changed to Boughton in the 1700s and as they moved west, although I've seen both spellings even within one family.
