She didn`t own it Joey, she leased it off the National Trust and then set it up as a Red Deer sanctuary, tasking a local fisherman with taking feed from the mainland, to the island to feed them.
What she didn`t factor in was that in the Winter, the sea is so rough a lot of the time, that the boats can`t launch. She also didn`t factor in that there is zero shelter on that island, not even trees or a wall.
So the Deer started to starve and faced with death or swimming to the mainland, they swam to the mainland and set themselves up in wooded area around by the main beach / golf course. ( my old man has been a member for decades )
She may have been prosecuted over it ?
Bear Gyllis bought the other island outright and still uses it, as a retreat for his family.
