But really, that is not a family history as such, it is just a collection of names and dates.
Family history is much more than a set of names and dates.
These were real people, who lived real lives, and were influenced by things and events around them, just as we are today. With a little more effort we can find much more about our ancestors. This is an excellent resource, but it has some severe limitations. First, it is an index only, second, it is far from complete, and third, it is somewhat prone to errors. For names and dates, there is simply no substitute for searches of the original parish records.
