Fly Emirates, mainly when touring historical record (6,4)

I believe the answer is:

family tree

I'm a little stuck... Click here to teach me more about this clue!

'historical record' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'fly emirates mainly when touring' is the wordplay.
'mainly' means to remove the last letter (virtually or mainly the word, but not all of it).
'when touring' indicates an anagram (letters travel or tour to different positions).
'fly'+'emirates'='flyemirates'
'flyemirates' with its last letter taken away is 'flyemirate'.
'flyemirate' is an anagram of 'FAMILY TREE'.

Can you help me to learn more?

(Other definitions for family tree that I've seen before include "Genealogical chart" , "Personal history" , "Chart of relations" .)
