Perhaps you should try some spelling variations:
"t.g browne" » "tho browne", "a.g brown", "g.j browne"
"a.w brown" » "a brown", "ann brown", "4.4 brown"
"a.b brown" » "4.4 brown", "6.6 brown", "6.8 brown"
"a.h brown" » "g.h brown", "nach brown", "a brown"
"a.r brown" » "j.r brown", "e.a.r brown", "fair brown"
"2.2 brown" » "12 brown", "2.2 brain", "2.2 broy"

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: (((((((("a.w brown") OR ("a.b brown"))) OR ("a.h brown"))) OR ("a.r brown"))) OR ((("2.2 brown") OR ("t.g browne")))).
• Removing quotes may allow a broader search: (((((((( a.w brown ) or ( a.b brown ))) or ( a.h brown ))) or ( a.r brown ))) or ((( 2.2 brown ) or ( t.g browne )))).
• Adding a wildcard symbol may retrieve word variants: (((((((("a.w brown") or ("a.b brown"))) or ("a.h brown"))) or ("a.r brown"))) or ((("2.2 brown") or ("t.g browne"))))*.
