First lady Bush
I believe the answer is:
laura
'first lady bush' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for laura that I've seen before include "Girl's name" , "- Ashley, Welsh clothes, furnishings designer" , "Cells of a group of recluses" , "girl" , "__ Ashley, Welsh fashion and textile designer, d. 1985" .)
