I doubt that the information I have is pertinent to your Conant line, but here's what I have.
Elijah Conant b, 12 March 1783 in Oakham,MA. removed to Barre, thence to New York.Married Nancy Taft. Only 2 children listed are: Robert Taft b 1 Sep 1810 Mary b. ____ d. 19 Jan 1881 m James R. Parsons
It is possible, of course, that Jeremiah was a child of thisElijah and was born after Robert Taft and was just not included in the book.
I found no Georges or George Washingtons connected to any Jeremiah
