Ada Finch is the mother of Silas Finch and Eugene (although the latter was adopted by Lucas soon after birth). Ada had a mysterious relationship with Mr. Edburt, as she knew his human name and was able to see him but did not have the characteristic blue eyes of people who were able to see him. She died by unknown causes at the age of 23 while Silas was still young and seems to have been friends with Odette'smother Rachel when they were younger.
