Jake's tricky because he was born on Earth, but if he moved around with Benjamin then he lived in space too, on various ships and DS9, but also Mars (Utopia Planitia shipyards) and even Romulus (Sisko had an embassy posting for a while). If I list Jake and Wesley as Boomers I might have to put Nog down for that too. Also, I'm not sure WHAT Wesley's deal was; if he had been moved around with Beverly and/or Jack Sr, then Picard would already have met him before TNG.
Picard did meet Wesley before TNG. Wesley was there when Picard came to break the news to Beverly Crusher about Jack Crusher's death.
