Read this article about Samuel Sedgwick.

Deborah Higgins is believed to be a descendant of Thomas Rogers of the Mayflower and his son Joseph. Their youngest son Elijah, in an interview with the genealogist George Sedgwick in April 1854, identified his mother as the dauaghter if Beriah Higgins and Desire Cooke. We don't have the source documentation to prove it. See this for more information.

Noel Sedgwick, son of Samuel Sedgwick and his second wife, apparently is the one who gave her name as Hannah Katherine Backer. However, baptismal records of the church at Kinderhook, New York, show the name to be "Catharina Bekker." Both Backer and Becker names are plentiful in the area at the time, so who knows which is her true name?

This means two previously undocumented children of Samuel Sedgwick and Hannah Katherine Backer. I assume they died young, or Noah would have known about them. So... I plan to ignore them for the time being, except to adjust the marriage date to about 1785. Contact me if you find anything about them. genealogy@sedgwick.org
