As first revealed by Chris Claremont in Uncanny X-Men #185, Rogue was born in Caldecott County, Mississippi. That county is fictional, and apart from the fact that it is rural and is situated directly on the river Mississippi we don't know a lot about it. As far as I know it is not clear which real-life Mississippi county it corresponds to.
What I would like to know is: Has Chris Claremont ever revealed how he hit upon the name? Checking in wikipedia, I see that there are a number of real-life places called Caldecott - four (plus a Caldecotte) in England, two in Singapore, one in Hong Kong - but only one in the US, to wit the Caldecott Tunnel near Oakland, CA. Wikipedia also lists nine persons with the surname Caldecott

Of these, the following two IMO may have been chosen by Claremont to name Rogue's home after:
Moyra Caldecott (1927-2015), a British author who wrote historical fiction, science-fiction and also non-fiction books about (mostly Celtic) mythology and folklore.

and
Randolph Caldecott (1846-1886), a British artist who specialised in children's book and after whom the Caldecott Medal, an annual prize for "the most distinguished American picture book for children", is named.

Can anyone shed light on this matter?
