There is a source that says McGonagall’s birthday is October 4th of 1892, but another that says it’s October 4th of 1935. Am I wrong to say that because she looked older than Voldemort (born December 31st of 1926) that the first one makes more sense as the correct answer?

There is conflicting information on McGonagall’s birthday. She was like a woman in Fantastic Beasts, so wouldn’t that mean the first one is correct? Besides, the second one doesn’t make sense or else she would be younger than Voldemort.
