Dedicated to aiding CORNELL/CORNWELL/CORNWALL family research in the U.S. and Canada.

Requesting information about families, particularly those in Columbia, Dutchess, Orange, Westchester and adjacent counties of New York, Connecticut and New Jersey before 1800.

Offering many records for ten families who emigrated to Ontario, Canada between 1790 and 1825 from the above area of New York (five connected to Thomas Cornell of Essex Co., England and MA, RI, NY) with many thousand individual descendants.

Those with an uncertain Cornell, Cornwell or Cornwall ancestry can benefit from an ongoing DNA project that may help pinpoint which family line they belong to.

Any who are pretty certain they descend from Thomas and Rebecca Cornell or William Cornwell of Middletown, CT can confirm their ancestry by being tested as well as help those of us still in doubt.

Completed testing provides evidence that the Cornell and Cornwall families share a common ancestor around 1500 and also that there are several other family lines unrelated to them but using the Cornell, Cornwall and Cornwell surnames. (Note that the Cornwell spelling is a variant used in both Cornell and Cornwall lines.)

Please note that a reduced price is available by joining this group prior to testing. Click on the following link for more information, or you are welcome to e-mail me.

In Nov. 2009, Bob Watts took a number of photographs of the old cemetery on the Cornell Homestead at Portsmouth, RI. It's entirely possible Thomas and Rebecca Cornell were interred here along with other early family members. There is clear evidence of 13 other burials in the form of badly eroded remnants of earlier grave stones - in many cases both head and foot stones. The link below will take you to a page where you can see the readable stones and the present state of this cemetery.

REBECCA CORNELL: Was She a Briggs?

The link below provides a discussion about Rebecca Cornell. Your participation is invited in this topic of general interest to Cornell researchers.

Also, be aware of the book titled "Killed Strangely, The Death of Rebecca Cornell" by Elaine Forman Crane, Cornell University Press, Ithaca & London, 2002, ISBN 0-8014-4002-5. It contains an interesting examination of the Cornell family at the time of this sad chapter in their lives. Highly recommended.



In 1867, Ezra Cornell had a notice printed to send Cornells who wrote him about his ancestry. Two researchers, Rowena Marten and Jane Knobloch, obtained copies of the notice from the Cornell University Library and provided them to me for this transcript.
