Interesting matter, really. You should read the topics on Lorkhan and the Shezarrines.

There says that the heroes may be representations of Lorkhan himself on Nirn, which is the only way he can manifest in the mortal plane. That's why they are not bound by many aspects of the world, and usually end up being more powerful than the rest of mortals.

So I think there is definitely a connection between them, but it doesn't seem logical for them to be the same person, given that they all must be alive at the same time. Check out the 3º Era timeline, you'll see that the gap of time between Arena and Oblivion is about 40 years. (And between Morrowind & Oblivion just 6). The only one set further in time is the dovahkiin, 200 years later. Anyway, a nice topic for a deeper research :D
