List of names to have an effect (8)

I believe the answer is:

I believe this clue is a double definition.

'list of names' is the first definition.
(eg a school register)

'have an effect' is the second definition.
(if something registers it has an effect or impact)

'to' is the link.

(Other definitions for register that I've seen before include "Official record of names, transactions" , "See 1" , "Annals" , "Official record of names etc." , "Obituary" .)

I've seen this clue in The Times.
