Gave daughter my macbook pro and 6plus for college & she is getting msgs etc under my name. What to do?
At a minimum you will need to make sure both devices are completely signed out of iCloud.  This will require your daughter knowing your iCloud password if she is not close by enough for you to do it.  I would recommend changing it immediately after if you do tell her.

Personally I would also do an Erase All Contents and Settings on the iPhone and a clean install on the MacBook Pro as well.
