I found this 70’s San Nicolas Island souvenir hoody sweatshirt recently, and never having heard of the place, did some googling.
Basically in the 1830s, her island was invaded by Russian fur trappers, and then soon evacuated by missionaries from Santa Barbara, but she somehow missed the boat. She survived on San Nicolas Island alone for 20 years, in a hut made of whale bones, until she was found and brought over to Santa Barbara in 1853, where she smiled and and sang songs and was very happy, by all accounts.
Until she died 7 weeks later from dysentery.
