27 estate » 7 estate, 1627 estate
12 john » 2 john
21 john » 1 john
25 john » 5 john, 15 john
2c john » c john, 20 john, 24 john
22 john » 2 john
11 john » 1 john
23 john » 13 john
3 john » 1 john, 4 john

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: %22orlebar%((((((2c john) OR (23 john))) OR (((((11 john) OR (((22 john) OR (12 john))))) OR (((25 john) OR (21 john))))))) OR (3 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (23 john))) or (((((11 john) or (((22 john) or (12 john))))) or (((25 john) OR (21 john))))))) or (3 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (23 john))) or (((((11 john) or (((22 john) or (12 john))))) or (((25 john) OR (21 john))))))) or (3 john)) %27 estate%22*.
