UNKNOWN MARKS - HISTORY

I am a newbie to silver and am not having any luck with these marks. The first appears to be a “B” inside the outline of another “B”. The 2nd mark appears to be an “A” with squiggle mark underneath. Any information regarding maker, history, pattern,etc…would be appreciated. These items also have an engraving on the back that reads “St. Elisabeth Club du Domino” if that helps any.
