In my opinion I think the curse of the Finch Family may have been the Finch surname. In a meaning Finch can mean death and curse rarely. As a result the ones without the Finch surname fates are unknown as Kay (Sam's divorced wife) and his 2nd wife who were theorized to have been set free from the curse. Sanjay wasn't cursed. Edith's mom was just cursed to actually marry him as he was an earthquake activist and would likely died anyway without marrying her. So Christopher his fate is unknown. Is the Finch surname cursed?
