This is what I have on the children of Benjamin Sneed and Felicia Oliver married December 27, 1790 in Halifax Co, Va: (I believe this information is from a couple of combined sources.)
1) Frances Sneed married Moses Ashbury. 2) John Sneed married Rosannah Meek November 24, 1825 in Washington Co, VA. 3) William Sneed b. abt 1790. 4) Henry Sneed b. abt 1793 married Jane Kestner. 5) Oliver Cline Sneed b. abt 1794 d. abt 1873 (Will probated in Russell Co, VA) married Rachael Kestner abt 1817. 6) Nickerson Sneed b. abt 1798 near Glade Springs, VA, married Elizabeth Beattie May 24, 1822 in Washington CO, VA.
I believe Benjamin Sneed was the son of Micajah Sneed Sr. and Sarah.Felicia Oliver was the daughter of Nickerson Olive and Elizabeth Durrett.
I am not sure this helps much, but good luck in your search.
