Jean Grey of the X-Men grew up in Annandale-on-Hudson, NY. Her parents were teachers at Bard College there.
Chris Claremont, longtime X-Men writer, is an alumni of Bard College. Nothing unusual with this connection. Lots of writers incorporate elements of their real life in their fiction.
But Claremont didn’t create Jean Grey. She was created as one of the original X-Men by Stan Lee and Jack Kirby back in 1963. Claremont didn’t begin writing the series until 1975.
So my question is did Claremont retcon Grey’s history or is it just a coincidence that Grey supposedly grew up in the same town he went to school in?
An important issue? No. But they can’t all be Great Debates.
