It's difficult to get back this far normally. I don't think you can rely on trees on the internet. Some people just pick up likely names and cobble the tree together with no verification whatsoever. And (to me) this is worse than useless.
Sometimes it's not how far back you can get, but what you can find out about you ancestors' lives that make this hobby so interesting. Things like how people lived at certain times, work, houses, furniture, clothes they wore, food they ate and how it was cooked and bought, washing arrangements etc etc. It can be very interesting. But that's just my opinion.
Just had a look at that website. I wouldn't place too much reliance on it.
