Mystery Monday: Her Voyage, Part III

Such clues there were to work with! Few made sense.
Her nephew has no mem'ry of the stunt
He called his mom about; the strange, intense
And quiet intonations, let's be blunt
Of those school children are in no known tongue.
Meanwhile, the captain has his own thing on
(It's gender reassignment, and it stung
His wife when he came clean about it). Gone
She still remains, and no one -- wait, what's this?
Dear list'ners, new reports keep coming in!
A man in Nova Scotia claims that Kris --
Yes, her, Miss Pollard -- all these years has been
An ageless resident of Digby town
Ere since the cornerstone was there laid down!
