I'm in the process of getting rid of some old books and comics. The other night I was thumbing through some Uncanny X Men issues, one of which includes the first appearance of the character Heather Hudson. One thing I noticed is how much she looked like Claire in those days, being a redhead with long hair and glasses. Then the thought came to mind is that she could be Claire's mom. Things got even more amusing when I found out that Heather Hudson and her husband had a little girl named Claire long after I stopped paying attention to the characters. I'm sure this is all coincidence, but I did find it interesting.
But Claire didn't transition until college (and I'm guessing that includes the social transition) so stories with a little girl already named Claire don't make a lot of sense. The coincidence is interesting though.
Well, we could imagine that the Heather Hudson in
our universe simply had somewhat different circumstances than the one in the QC universe. Ours had a daughter named Claire, theirs had a son who eventually
became a daughter named Claire...
But that would be taking an interesting coincidence far more seriously than it deserves, IMHO.
