Organised tour around daughter's house (5)
I believe the answer is:
tudor
'house' is the definition.
(royal house)
'organised tour around daughter's' is the wordplay.
'organised' indicates anagramming the letters.
'around' is an insertion indicator.
'daughter' becomes 'd' (genealogical abbreviation).
'tour' with letters rearranged gives 'tuor'.
'tuor' placed around 'd' is 'TUDOR'.
(Other definitions for tudor that I've seen before include "Mary" , "Pre-Stuart royal house" , "Dynasty on the English throne 1485-1603" , "Former English royal house" , "Relating to the English ruling family in the 1500s" .)
