Correct my storyline understanding? D1 > D2 > D2LOD > D3 [Spoilers]

[Mavfin]

Lazarus used this chaos to abduct Leoric's son, a prince whose name I don't recall.

Prince Albrecht.

I won't spoil the details (they're out there in forums/youtube if you want them), but in D3 you find out that Leoric had more than one son involved in the story...

Edit: I'm enjoying the spoilers I see, because, it's only a little piece of the game that we can see, so it's only a few little things you can find out. However, I won't post them here, beyond the above tidbit.
