I have heard both on the Harrison name, one it could be a middle name after family members, and or it could be a married name.
Since we can not prove who Elizabeth Harrison Blair's parents are (possible; Alexander Blair and Elizabeth Breeding); we thought maybe the possibility of Harrison being a married name.....even though she was married to Absolem Randolph about the age of 16....

Just kicking some ideas around as we are at our "Brick Wall", with both Absolem Randolph and Elizabeth Harrison Blair Randolph....my 4th great grandparents...
