I did a dig on a tiny island near Christchurch, NZ a while ago because it reminded me so much of the shape of Little St James Island and it was near a city named"Christchurch."
Christchurch NZ is known as The Garden City
Nearby Quail Island was used as dog quarantine for Antartic expeditions.
Currently has replica dog kennels.
Island was originally Otamahua, where native children hunted eggs.
"Christchurch" shares a name with the schools from the Hampstead Cover-Up children's testimony and where Alice Lydell's father worked.
I'm not coming to any conclusion. Just found it interesting.
