A thought about Marauder's Map

Do we actually know when George and Fred obtained Marauder's Map?  If they
had it in their possession during SS/PS, what do you think it would have
said about Professor Quirrell and Lord Voldemort possessing the same body?
I am just trying to anticipate future scenarios.

A side note:  Lupin said that in PoA that he saw Wormtail on the map and
that is why he knew he was still alive.  If Hermione would have had the map
she would have discovered earlier that Rita Skeeter was an Animagi. I guess
Marauder's Map is a really important aspect of the story.  I wonder if Lord
Voldemort knows that it exists.
