You should be using ExtJS Models, and Associations, in particular the HasOne association.

Documentation:

http://docs.sencha.com/ext-js/4-1/#!/api/Ext.data.association.HasOne

Example:

Ext.define('Person', {
    extend: 'Ext.data.Model',
    fields: [
        'id',
        'first_name',
        'last_name'
        ],

    hasOne: [
        {
        name: 'marital',
        model: 'Marital',
        associationKey: 'marital' // <- this is the same as what is in the JSON response
        }
    ],

    proxy: {
        type: 'ajax',
        url: 'whatever',
        reader: {
            type: 'json',
            root: 'items' // <- same as in the JSON response
        }
    }
});
