David's wife, mother of Solomon (9)
I believe the answer is:
bathsheba
I believe this is a double definition.
'david's wife' is the first definition.
(wife of King David in the Bible)
'mother of solomon' is the second definition.
(Old Testament, wife of King David)
(Other definitions for bathsheba that I've seen before include "who married David?" , "female partner in affair" , "David's wife" , "biblical character" , "Wife of Uriah" .)
