These data indicate:

Gender and Type	Age Class	Therefore Born	Individuals Inferred
2 free white males	15 or under	1774-1790	= Son A = Son B
2 free white females	all ages	in or bef. 1790	= Comfort? = Daughter A

This record may not be Comfort as there were other KENNISTONs in Rockingham Co. during this period.  Also in the 1790 Census of Newmarket:  Aaron KENNISTON (2-1-5-0-0) and Jonathan KENNISTON (2-1-2-0-0).  The list has been alphabetized, so no neighborhood reconstruction is possible.

Jonathan KENISTON Birth: 28 Jan 1771, Newmarket Twp, Rockingham, New Hampshire Source: Index to births, early to 1900. New Hampshire. Registrar of Vital Statistics.

Why-oh-why didn't they record the parents?!  Jonathan is the right age to be a son of Valentine and Comfort.

4.  Broderbund.  World Family Trees.  Someone has submitted pedigrees containing Valetine KINNISTON(s), sometimes with wife Comfort SIAS, no less than ten times to WFT:  8(1887), 9(2006, 2007, 2009, 2010), 15(1732), 22(1867, 1868, 1869), and 29(811).  These have to be the most botched up pedigrees I have ever seen, both from the standpoint of the person's obvious inability to use the FTM software and with regards to content.  There are husbands dying the day their wife was born, children born five years after their grandmother was born, spouses attached multiple times, incorrect genders, and so on.  There may be some truth somewhere in these pedigrees, but nothing in them can be trusted without verification.  It's too bad, really, because this person probably has some worthwhile information — on a branch of the family no one else seems to be researching and in which I'm interested — and is obviously trying to share it.  They need to get some help.

5.  Ancestry World Trees [now WorldConnect] (online at Ancestry.com).  The same person submitting pedigrees to WFT seems also to have submitted them to AWT.
