I haven't tested this, but I think something like this would do what you want:

import org.codehaus.jackson.node.ObjectNode;
// ...
for (JsonNode personNode : rootNode) {
    if (personNode instanceof ObjectNode) {
        ObjectNode object = (ObjectNode) personNode;
        object.remove("familyName");
        object.remove("middleName");
    }
}

You could also do this more efficiently using Jackon's raw parsing API, but the code would be a lot messier.
