If you happen to tag any of the royal lines you have a wealth of information available to you and history takes on a new meaning. I agree with John in Kansas, It has a ways to go before they can say for sure on anything. However, the needed info comes from YOU! The more data they obtain with verifiable genealogies the better it will become. So, if you don't discover much the first go around your data is in there and after a period of time you should see some more refined results.
