Replying to... Montavilla47:
"And, at that point, it doesn't matter whether they are
memory-charmed or not."

Surely the main point of the charm was threefold.

So that, if found, they couldn't tell anything useful
To make it less likely that they would be found, as if they can't 
remember, they can't accidentally let anything slip which might come to 
the attention of a witch or wizard.  It's hard, even for those who have 
been trained to do it, to keep a different identity 24/7.
To make sure that they didn't miss her if she died

All three may be flawed, but in a desperate situation people do 
desperate things to try to protect the ones they love.
