Who came to magic late in life?

I don't think it is Merope.  The only character that fits this
description is Trelawney.  If you recall it has always been said that
the wizarding world does not believe in clairvoyance.  DD even said
that he thought she was her prophecy was only made true because LV
chose to do so. In going after Harry he made the Prophecy true.  Had
Snape never told him about it it would not have happened.  The fight
scene in Hogwarts is the only time we have seen her use actual magic.
 Plus I would think that late in life means her.
