Perhaps you should try some spelling variations:
1688 estate » 1636 estate, 1650 estate, 1778 estate
1627 estate » 1636 estate, 1650 estate, 1721 estate
27 estate » 7 estate
2c john » c john, 22 john, 21 john
23 john » 3 john, 13 john
12 john » 2 john, 16 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 (1 john))) OR (((12 john) OR (10 john)))) %((27 estate) OR (((1627 estate) OR (1688 estate))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (23 john))) or (1 john))) or (((12 john) or (10 john)))) %((27 estate) or (((1627 estate) OR (1688 estate))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (23 john))) or (1 john))) or (((12 john) or (10 john)))) %((27 estate) or (((1627 estate) OR (1688 estate))))%22*.
