A number of websites list Evelyn Adama as Bill Adama's mother. Granted we could assume that this is the case, given that
- Evelyn was present at the ceremony with Bill shown in the "Caprica" epilogue
- Joseph and Evelyn were dating as of the end of "Caprica".
However I can't find any official confirmation that Bill's mother was called "Evelyn" either in the main series or in "Blood and Chrome". Has this ever been confirmed anywhere in canon or official sources, or is it just an assumption?
