Where were Spike and Dru when Angelus and Darla met Elizabeth and James?

Do we know where Spike and Drusilla had been when Angelus and Darla had became friends with Elizabeth and James?

I'm pretty sure that Spike and Dru hadn't been born yet. And though I don't think it's shown, Elizabeth and James went their own way before Spike and Dru were, er, recruited.
