I'm not sure if it says it says this anywhere, they don't have it on the Lexicon, but would McGonagall still be Head of Hogwarts when Rose Weasley was in Hogwarts?

Rose starts going to Hogwarts 2017 and McGonagall was born 1925. This would make her 92. But seeing as wizards usually live through their 100's (at least I remember this being said) it would be plausible that she was still Headmistress, right?
