James Burnett Cooper was born on September 30 1828 in Shoreham, Vermont  and died on May 31, 1897 in Colorado Springs, Colorado.  He married Jennett Clark (one reference lists his wife as Jennett McNeil) who was born on October 2, 1826 in New York and died on May 2, 1892 in Alameda, California.  They were married on June 17, 1852 in New Berlin, Wisconsin.   

James Burnett Cooper was the oldest son in the Cooper family and spent most of his life mining and lived in California. 

One of the children (We don't know whether or not there were more children) of James Burnett Cooper and Jennett Clark was Alexander Burnett Cooper.  Alexander Burnett Cooper was born February 12, 1857 at Faribault, Minnesota and died on August 26, 1929 in San Francisco, California.  He married Emma Jennett Cheney who was born on July 11, 1855 at Prospect Hill, Wisconsin and died on August 25, 1913 at San Francisco, California.  They were married on May 17, 1876 at Alameda, California.  Alexander Burnett Cooper and Emma Jennett Cheney had at least one child. 

That child was named Ethel Caro Cooper.  There is a reference to her in the Proceedings of the 20th Continental Congress of the Daughters of the American Revolution in Washington, D.C. April 17-22, 1911 Page 508 which states:

Tamalpis, San Francisco.  Regent, Miss Ethel Caro Cooper.

In September of 1974 a great-great-granddaughter of James Burnett Cooper wrote a letter from Florida to the Griggs County Historical Society.  In her letter she states a distant cousin, Robert L. Cooper, who is a grandson of Henry Cooper, has two young sons, who are the last of Thomas and Caroline Cooper's descendants to bear the name of Cooper.
