JSON invalid character '}' looking for beginning of object key string

Use any JSON validator like http://jsonlint.com/ to validate your JSON.

Correct JSON is:

{
  "results": [{
     "nameChunk1": [{
        "name1": "Sean",
        "name2": "Noah" 
     }],
     "nameChunk2": [{
       "name1": "Joseph",
       "name2": "Sam"
     }]
  }]
}

Correct your JSON syntax:

{
  "results": [{
     "nameChunk1": [{
        "name1": "Sean",
        "name2": "Noah" 
     }],
     "nameChunk2": [{
       "name1": "Joseph",
       "name2": "Sam"
     }]
  }]
}

Observe that I have added , after each array.. and removed , after name2 key.

Always use validators such as http://jsonlint.com/ to validate your JSON.
