Find an object and it's properties within a larger object with javascript/jquery
===

    family = {
      'person1':[{"id":"1111","name":"adam", "sex":"male", "born":"USA"}],
      'person2':[{"id":"2222","name":"sarah", "sex":"female", "born":"Canada"}],
      'person3':[{"id":"3333","name":"adam", "sex":"male", "born":"USA"}]
    };

Given the family object above, how do I extra all the properties (id, name, sex, born) of one of the person objects that have a specific id (or name) value? eg id=1111

So ideally I can get a new object personInQuestion that I can manipulate, where:
personInQuestion = {"id":"1111","name":"adam", "sex":"male", "born":"USA"}

Thank you
