There is a book out there called Virginia Wills before 1799 A Complete Abstract Register of all Names.
And when they say abstract, they mean abstract. It gives the name of the deceased, probate date, maybe date of will, wife, if any, and children's name. Not exactly everything you would want to read, but it something anyway.
Campbell County Will Book December 6, 1786
sons: William, John, James daughters Jane and Mary Perrin
and Mary Perrin's children Charles Perrin, Robert Perrin
So we know that Robert Baber's place of residence was most likely Campbell County, Virginia. That would be where to search.
I found at the Tenessee Archives a book Sullivan County Tennessee marriages from 1863 to 1893
Sallie Dove married James McMinnis December 21, 1881.
John Dove married Susan A. Large January 5, 1887
These are probably James and Almira's children.
I have been searching in the Pittsylvania County, Virginia records also.
Pittsylvania County Marriages Page 1
William Abston and Sarah Dove Daughter of George Dove married May 5, 1826
Booker Keesee and Jane Dove Daughter of George Dove married February 21, 1814 page 89
William Roach and Peggy Dove Daughter of George Dove married January 28, 1813 page 132
George Dove and Caty Bruce Surety James Bruce. Married December 17, 1804
This George Dove could possibly be the father of Sarah, but I don't think he could be the father of Jane and Peggy unless he was married to someone else before he married Caty Bruce.
I believe that there was a George Dove, William Dove and a Leonard Dove living in Pittsylvania County at the beginning of the nineteenth century.
Tradition use to be that the oldest son was named after their grandfather. Now we know that James Dove was the father of our George Dove that married Cornelia Ward. And it looks like George Dove was the oldest child. Could this George Dove be the grandfather of George. Of course, this will need further investigation.
