I'm pretty sure that Paul adopted Linda's daughter so her name would be Heather McCartney. However, she's most likely married now and has a different last name anyway. I would imagine that for professional reasons, Heather Mills may continue to go by Mills or perhaps due a hyphen thing ie. Mills-McCartney.
In any case, I wish the new bride and groom all the happiness in the world. Paul certainly deserves it after a rough few years......losing Linda and then George.
