Dr. Thomas James

I am researching the James Family from Schoharie County New York.

I am running into a dead end.

Here is a direct descendant list:

William Robert James - born 1960  (me) birthplace Boston

Robert Edgar James b. 1925 - d. 2005 birthplace Chicago

Gordon Edgar James b. 1893 - d.1964 birthplace Gloversville, NY

Edgar Ackley James b. 1860 - d. 1944 birthplace NY

Alanson Leonard James b. 1831 - d.1898 birthplace NY

Dr. Thomas James b. 1787? - d. ???? birthplace CT/RI

I thought perhaps Dr. James may be related to Captian John James and Esther Denison.  I keep running into walls.  Any help/guidance would be appreciated.

Dr. James is listed in the 1850 census in Schoharie County, NY according to the record was was 63.

Thanks for reading and for your time.
