128 bishop » 1748 bishop, 1725 bishop, 11 bishop
a.h bishop » arch bishop, nach bishop, a bishop
21 bishop » 11 bishop, a bishop, d bishop
25 saint » 5 saint, 15 saint, 2015 saint
21 saint » 2 saint, 2013 saint, 2015 saint

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((25 saint) OR (1 saint))) OR (21 saint))%((((a.h bishop) OR (128 bishop))) OR (((21 bishop) OR (_ bishop)))) of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((25 saint) or (1 saint))) or (21 saint))%((((a.h bishop) or (128 bishop))) or (((21 bishop) OR (_ bishop)))) of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((25 saint) or (1 saint))) or (21 saint))%((((a.h bishop) or (128 bishop))) or (((21 bishop) OR (_ bishop)))) of smyrna%22*.
