For what it's worth, I have in my notes a little about the individuals you name. John Witt Morris, Sr. married Frances Hormilla Ferguson. She was born ca. 1852/1855, and died September 4, 1936. The family is listed in the 1960 Appomattox County, VA census. Their son, John Witt Morris, Jr. married Gracie Brightwell, daughter of Thomas Jefferson Brightwell and Florence Tanner, in 1913 in Appomattox County. (My maternal grandfather was a Brightwell, and I found this information while researching that name.)
In the Featherston book, there are many families of Ferguson and Morris; however, I don't see mention J. W. Morris or of Frances Ferguson. I do see the following pertaining to Smith on page 258:
[Parents and siblings of Elbert Smith:]
SMITH, ELIJAH, 1844-1906, Married Margaret Ferguson, 1845-1909. Children:
Ollie Thomas, 1870-1946, Married Mary O'Brien. Second wife: Rena Wood;
Lucy, 1872, Married Sam Doss;
LaFeyette, 1871, Married Mamie Martin. Second wife: Berta Wright;
Juttie, 1877-1946, Married John Wright; Laura, 1879-1907; Ruth, 1880, Married C. L. Johnson;
and Elbert, 1882-1914, Married Addie Hamilton. Second wife: Mattie Morris.
Lots of Smith families, but I don't see any other reference to Elijah. None to an Eliza or to an Elisha.
If you have nothing on these families, you may want to start searching the census records. I'll keep in touch.
