Looking for information on Iris Thrane. She was the daughter of Robert Paoli Thrane of the well known Thrane family from the Oslo, Norway area. Her great-grandfather was the activist in the labor movement in Norway, Marcus Moller Thrane.
Think her mother was Hermoine Moss, of English birth.
Iris was born in New York City on 11 January 1910.
Any help would be appreciated.
