I just saw your message. I can give that information. Annie E. Blankenship was married to John W. Blankenship he is a brother to my Great Great Grandfather, Richard G. Blankenship. I have her listed as Ann Elizabeth on the 1850 Census in Lauderdale County, Tennessee; In 1860 they are in Haywood County, Tennessee; In 1870 they are back in Lauderdale County, Tennessee , they have a Matilda Vaden in their household, 1880 they are in Lamar Texas.
I came across the Will of D.D. Vaden who lists a daughter Elizabeth Ann and a daughter Matilda who is the same age as the Matilda in John and Ann's household. (www.Genforum.com)

John and Ann(ie) had 10 Children from what I could find, Thomas G. born abt 1850
Mary
Joseph
Matilda
Elen
Josiah
Mariah
Johanna b. 28 Jun 1866 d.Guymon, Texas County, Oklahoma
