In the harbour area of BG city I have come across two separate characters who do not want to speak to my group.

Their names are Kolvar and Cordyr.

I do not recall meeting them in previous games. Can anyone enlighten me ?

I think Cordyr only talks to you if you're evil. Don't know about the other one.

Found this:

"Cordyr has been having some trouble with Sirines far to the south. If the party has a low or medium reputation, he'll ask them to get rid of them."

Well, that explains why Cordyr does not want to talk to my group - it has a reputation of 20. Come to think of it, I vaguely remember him complaining about the sirines during a previous game (in that game, my group was evil aligned).

That still leaves Kolvar. I think I met him at the gate near the Iron Throne. Does anyone know what he is doing there ?

I seem to remember someone with that sort of name hanging around that area--but only in Chapter 7. He works for a certain organization, and if you have Xzar or Montaron in your group, he has something to say to them. I'm not 100% sure, though.
